-## Known bugs on KVM enabled qemu
-
-The `x86_64` reference code runs fine in qemu soft-cpu, but has serious issues
-when using KVM mode on some machines. The workaround is to *not* place
-page-tables in ROM, as done in
-[CB:49228](https://review.coreboot.org/c/coreboot/+/49228).
-
-Here's a list of known issues:
-
-* After entering long mode, the FPU doesn't work anymore, including accessing
-  MMX registers. It works fine before entering long mode. It works fine when
-  switching back to protected mode. Other registers, like SSE registers, are
-  working fine.
-* Reading from virtual memory, when the page tables are stored in ROM, causes
-  the MMU to abort the "page table walking" mechanism when the lower address
-  bits of the virtual address to be translated have a specific pattern.
-  Instead of loading the correct physical page, the one containing the
-  page tables in ROM will be loaded and used, which breaks code and data as
-  the page table doesn't contain the expected data. This in turn leads to
-  undefined behaviour whenever the 'wrong' address is being read.
-* Disabling paging in compability mode crashes the CPU.
-* Returning from long mode to compability mode crashes the CPU.
-* Entering long mode crashes on AMD host platforms.

-# cbfstool: Handling memory mapped boot media
-
-`cbfstool` is a utility used for managing coreboot file system (CBFS)
-components in a ROM image. x86 platforms are special since they have
-the SPI flash boot media memory mapped into host address space at
-runtime. This requires `cbfstool` to deal with two separate address
-spaces for any CBFS components that are eXecute-In-Place (XIP) - one
-is the SPI flash address space and other is the host address space
-where the SPI flash gets mapped.
-
-By default, all x86 platforms map a maximum of 16MiB of SPI flash at
-the top of 4G in host address space. If the flash is greater than
-16MiB, then only the top 16MiB of the flash is mapped in the host
-address space. If the flash is smaller than 16MiB, then the entire SPI
-flash is mapped at the top of 4G and the rest of the space remains
-unused.
-
-In more recent platforms like Tiger Lake (TGL), it is possible to map
-more than 16MiB of SPI flash. Since the host address space has legacy
-fixed device addresses mapped below `4G - 16M`, the SPI flash is split
-into separate windows when being mapped to the host address space.
-Default decode window of maximum 16MiB size still lives just below the
-4G boundary. The additional decode window is free to live in any
-available MMIO space that the SoC chooses.
-
-Following diagram shows different combinations of SPI flash being
-mapped into host address space when using multiple windows:
-
-![MMAP window combinations with different flash sizes][mmap_windows]
-
-*(a) SPI flash of size 16MiB (b) SPI flash smaller than 16MiB (c) SPI flash
-of size (16MiB+ext window size) (d) SPI flash smaller than (16MiB+ext
-window size)*
-
-The location of standard decode window is fixed in host address space
-`(4G - 16M) to 4G`. However, the platform is free to choose where the
-extended window lives in the host address space. Since `cbfstool`
-needs to know the exact location of the extended window, it allows the
-platform to pass in two parameters `ext-win-base` and `ext-win-size`
-that provide the base and the size of the extended window in host
-address space.
-
-`cbfstool` creates two memory map windows using the knowledge about the
-standard decode window and the information passed in by the platform
-about the extended decode window. These windows are useful in
-converting addresses from one space to another (flash space and host
-space) when dealing with XIP components.
-
-## Assumptions
-
-1. Top 16MiB is still decoded in the fixed decode window just below 4G
-   boundary.
-1. Rest of the SPI flash below the top 16MiB is mapped at the top of
-   the extended window. Even though the platform might support a
-   larger extended window, the SPI flash part used by the mainboard
-   might not be large enough to be mapped in the entire window. In
-   such cases, the mapping is assumed to be in the top part of the
-   extended window with the bottom part remaining unused.
-
-## Example
-
-If the platform supports extended window and the SPI flash size is
-greater, then `cbfstool` creates a mapping for the extended window as
-well.
-
-```
-ext_win_base = 0xF8000000
-ext_win_size = 32 * MiB
-ext_win_limit = ext_win_base + ext_win_size - 1 = 0xF9FFFFFF
-```
-
-If SPI flash is 32MiB, then top 16MiB is mapped from `0xFF000000 -
-0xFFFFFFFF` whereas the bottom 16MiB is mapped from `0xF9000000 -
-0xF9FFFFFF`. The extended window `0xF8000000 - 0xF8FFFFFF` remains
-unused.

-# Beaglebone Black
-This page gives some details about the [BeagleBone Black] coreboot port and
-describes how to build and run it.
-
-The port currently only supports booting coreboot from a micro SD card and has
-some other limitations listed below.
-
-## Supported Boards
-The Beaglebone port supports the following boards:
-
-- Beaglebone Black
-- Beaglebone Black Wireless
-- Beaglebone Pocket (untested, may need tweaking)
-- Beaglebone Blue (untested, may need tweaking)
-- Beaglebone Original (untested, may need tweaking)
-
-## Use Cases
-This port was primarily developed as a learning exercise and there is
-potentially little reason to use it compared to the defacto bootloader choice of
-U-Boot. However, it does have some interesting practical use cases compared to
-U-Boot:
-
-1. Choosing coreboot as a lightweight alternative to U-Boot. In this case,
-   coreboot is used to do the absolute minimum necessary to boot Linux, forgoing
-   some U-Boot features and functionality. Complex boot logic can then instead
-   be moved into Linux where it can be more flexibly and safely executed. This
-   is essentially the LinuxBoot philosophy. [U-Boot Falcon mode] has similar
-   goals to this as well.
-2. Facilitating experimenting with coreboot on real hardware. The Beaglebone
-   Black is widely available at a low pricepoint (~$65) making it a great way to
-   experiment with coreboot on real ARMv7 hardware. It also works well as a
-   development platform as it has exposed pads for JTAG and, due to the way it
-   boots, is effectively impossible to brick.
-3. The Beaglebone Black is often used as a external flasher and EHCI debug
-   gadget in the coreboot community, so many members have access to it and can
-   use it as a reference platform.
-
-## Quickstart
-1. Run `make menuconfig` and select _TI_/_Beaglebone_ in the _Mainboard_ menu.
-2. Add a payload as normal.
-3. Run `make`.
-4. Copy the resulting `build/MLO` file to the micro SD card at offset 128k - ie
-   `dd if=build/MLO of=/dev/sdcard seek=1 bs=128k`.
-
-**NOTE**: By default, the Beaglebone is configured to try to boot first from
-eMMC before booting from SD card. To ensure that the Beaglebone boots from SD,
-either erase the internal eMMC or hold the _S2_ button while powering on (note
-that this has to be while powering on - ie when plugging in the USB or DC barrel
-jack - the boot order doesn't change on reset) to prioritize SD in the boot
-order.
-
-## Serial Console
-By default, coreboot uses UART0 as the serial console. UART0 is available
-through the J1 header on both the Beaglebone Black and Beaglebone Black
-Wireless. The serial runs at 3.3V and 115200 8n1.
-
-The pin mapping is shown below for J1.
-
-    ```eval_rst
-    +----------------------------+------------+
-    | Pin number                 | Function   |
-    +============================+============+
-    | 1 (Closest to barrel jack) | GND        |
-    +----------------------------+------------+
-    | 4                          | RX         |
-    +----------------------------+------------+
-    | 5                          | TX         |
-    +----------------------------+------------+
-    ```
-
-## Boot Process
-The AM335x contains ROM code to allow booting in a number of different
-configurations. More information about the boot ROM code can be found in the
-AM335x technical reference manual (_SPRUH73Q_) in the _Initialization_ section.
-
-This coreboot port is currently configured to boot in "SD Raw Mode" where the
-boot binary, with header ("Table of Contents" in TI's nomenclature), is placed
-at the offset of 0x20000 (128KB) on the SD card. The boot ROM loads the coreboot
-bootblock stage into SRAM and executes it.
-
-The bootblock and subsequent romstage and ramstage coreboot stages expect that
-the coreboot image, containing the CBFS, is located at 0x20000 on the SD card.
-All stages directly read from the SD card in order to load the next stage in
-sequence.
-
-## Clock Initialization and PMIC
-To simplify the port, the TPS65217C Power Management IC (PMIC) on the Beaglebone
-Black is not configured by coreboot. By default, the PMIC reset values for
-VDD_MPU (1.1V) and VDD_CORE (1.8V) are within the Operating Performance Point
-(OPP) for the MPU PLL configuration set by the boot ROM of 500 MHz.
-
-When using Linux as a payload, the kernel will appropriately scale the core
-voltages for the desired MPU clock frequency as defined in the device tree.
-
-One significant difference because of this to the U-Boot port is that the DCDC1
-rail that powers the DDR3 RAM will be 1.5V by default. The Micron DDR3 supports
-both 1.35V and 1.5V and U-Boot makes use of this by setting it to 1.35V to
-conserve power. Fortunately, Linux is again able to configure this rail but it
-involves adding an entry to the device tree:
-
-    &dcdc1_reg {
-    regulator-name = "vdd_ddr3";
-    regulator-min-microvolt = <1350000>;
-    regulator-max-microvolt = <1350000>;
-    regulator-boot-on;
-    regulator-always-on;
-    };
-
-If this port was to be extended to work with boards or SoCs with different
-requirements for the MPU clock frequency or different Operating Performance
-Points, then the port may need to be extended to set the core voltages and MPU
-PLL within coreboot, prior to loading a payload. Extending coreboot so that it
-can configure the PMIC would also be necessary if there was a requirement for
-coreboot to run at a different MPU frequency than the 500 MHz set by the boot
-ROM.
-
-# Todo
-- Allow coreboot to run from the Beaglebone Black's internal eMMC. This would
-  require updating the `mmc.c` driver to support running from both SD and eMMC.
-- Support the boot ROMs *FAT mode* so that the coreboot binary can be placed on
-  a FAT partition.
-- Increase the MMC read speed, it currently takes ~15s to read ~20MB which is a
-  bit slow. To do this, it should be possible to update the MMC driver to:
-    - Increase the supported blocksize (currently is always set to 1)
-    - Support 4-bit data width (currently only supports 1-bit data width)
-- Convert the while loops in the MMC driver to timeout so that coreboot does not
-  hang on a bad SD card or when the SD card is removed during boot.
