Address region from 0x0 to 0x00ffffff is used for IROM_LOVEC and can not be accessed by Bootloader. Issue found in CL: 283104 is captured by this patch. BUG=None BRANCH=None TEST=Compiles successfully and reboot test does not crash in firmware Here are memory mapping table before and after this CL for evt2 board: Before: Mapping address range [0000000000000000:0000000040000000) as cacheable | read-write | secure | device Mapping address range [0000000040000000:0000000040040000) as cacheable | read-write | non-secure | normal Mapping address range [0000000040040000:0000000080000000) as cacheable | read-write | secure | device Mapping address range [0000000080000000:00000000feb00000) as cacheable | read-write | non-secure | normal Mapping address range [00000000fec00000:0000000100000000) as cacheable | read-write | secure | normal Mapping address range [0000000100000000:0000000140000000) as cacheable | read-write | non-secure | normal After: Mapping address range [0000000001000000:0000000040000000) as cacheable | read-write | secure | device Mapping address range [0000000040000000:0000000040040000) as cacheable | read-write | non-secure | normal Mapping address range [0000000040040000:0000000080000000) as cacheable | read-write | secure | device Mapping address range [0000000080000000:00000000feb00000) as cacheable | read-write | non-secure | normal Mapping address range [00000000fec00000:0000000100000000) as cacheable | read-write | secure | normal Mapping address range [0000000100000000:0000000140000000) as cacheable | read-write | non-secure | normal Signed-off-by: Jimmy Zhang <jimmzhang@nvidia.com> Change-Id: I07d38a8994c37bf945a68fb95a156c13f435ded2 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: 3eee44944c2c83cc3530bfac0d71b86d3265f5b2 Original-Change-Id: I2b827064807ed715625af627db1826c3a01121ec Original-Signed-off-by: Jimmy Zhang <jimmzhang@nvidia.com> Original-Reviewed-on: https://chromium-review.googlesource.com/285260 Original-Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: http://review.coreboot.org/11015 Reviewed-by: Furquan Shaikh <furquan@google.com> Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net>
------------------------------------------------------------------------------- coreboot README ------------------------------------------------------------------------------- coreboot is a Free Software project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload. With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required. coreboot was formerly known as LinuxBIOS. Payloads -------- After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot. See http://www.coreboot.org/Payloads for a list of supported payloads. Supported Hardware ------------------ coreboot supports a wide range of chipsets, devices, and mainboards. For details please consult: * http://www.coreboot.org/Supported_Motherboards * http://www.coreboot.org/Supported_Chipsets_and_Devices Build Requirements ------------------ * gcc / g++ * make Optional: * doxygen (for generating/viewing documentation) * iasl (for targets with ACPI support) * gdb (for better debugging facilities on some targets) * ncurses (for 'make menuconfig') * flex and bison (for regenerating parsers) Building coreboot ----------------- Please consult http://www.coreboot.org/Build_HOWTO for details. Testing coreboot Without Modifying Your Hardware ------------------------------------------------ If you want to test coreboot without any risks before you really decide to use it on your hardware, you can use the QEMU system emulator to run coreboot virtually in QEMU. Please see http://www.coreboot.org/QEMU for details. Website and Mailing List ------------------------ Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website: http://www.coreboot.org You can contact us directly on the coreboot mailing list: http://www.coreboot.org/Mailinglist Copyright and License --------------------- The copyright on coreboot is owned by quite a large number of individual developers and companies.
