This is a µATX mainboard with a LGA1151 socket and two DDR4 DIMM slots.
There are two possible BOM configurations: Sid has no legacy devices,
whereas Manny provides two serial ports, a parallel port, a PCI slot
and PS/2 keyboard/mouse connectors. These boards also have different
Super I/O models: Manny uses an ITE IT8625E, whereas legacy-free Sid
comes with an ITE IT8656E instead.
This coreboot port has been done using a Sid board, thus support for
Manny-specific features is missing. Booting should still be possible,
though: none of these legacy features is essential.
The board has an unpopulated 6-pin header, wired to PCH UART 2. This
can be used to retrieve coreboot logs.
Working:
- Both DIMM slots (Micron CT4G4DFS8213.8FA11, Hynix HMA851U6AFR6N-UH)
- PCH SerialIO UART 2 to get coreboot logs
- Rear USB ports
- Realtek RTL8111 GbE NIC
- Integrated graphics on DVI with libgfxinit
- At least one SATA port
- Flashing internally with flashrom
- S3 suspend/resume
- VBT
- SeaBIOS 1.14 to boot Arch Linux (kernel linux-5.10.15.arch1-1)
Untested:
- Audio
- VGA: DP2VGA chip uses DDI E, and libgfxinit doesn't support DDI E yet
- Front USB headers
- Non-Linux OSes
- PCI slot
- IT8625E peripherals: serial, parallel and PS/2 ports

This patch changes the memlayout macro infrastructure so that the size
of a region "xxx" (i.e. the distance between the symbols _xxx and _exxx)
is stored in a separate _xxx_size symbol. This has the advantage that
region sizes can be used inside static initializers, and also saves an
extra subtraction at runtime. Since linker symbols can only be treated
as addresses (not as raw integers) by C, retain the REGION_SIZE()
accessor macro to hide the necessary typecast.

This adds initial support for the Pine64 ROCKPro64 board.
The ROCKPro64 (http://pine64.org/rockpro64) is a SBC using the
RK3399 SoC with up to 4GB LPDDR4.
So far only the bootblock part works, the romstage starts to execute,
though.
For ramstage to work we'll need to port some of the changes required
for LPDDR4 vs LPDDR3. This will be addressed in follow up changes.
UART2 on the PI-2 connector can be used as a coreboot console.
GND is pin 6
TXD is pin 8
RXD is pin 10
Flashing:
I used an OpenWRT nightly for the ROCKPro64 and its builtin tool.
$ mtd write coreboot.rom /dev/mtd0
Recovering from a bad flash:
To recover from a bad flash bridging pins 23 and 25 on the PI-2
connector will make the board boot from SD card.

cbfstool has always had a CBFS_FILENAME_ALIGN that forces the filename
field to be aligned upwards to the next 16-byte boundary. This was
presumably done to align the file contents (which used to come
immediately after the filename field).
However, this hasn't really worked right ever since we introduced CBFS
attributes. Attributes come between the filename and the contents, so
what this code currently does is fill up the filename field with extra
NUL-bytes to the boundary, and then just put the attributes behind it
with whatever size they may be. The file contents don't end up with any
alignment guarantee and the filename field is just wasting space.
This patch removes the old FILENAME_ALIGN, and instead adds a new
alignment of 4 for the attributes. 4 seems like a reasonable alignment
to enforce since all existing attributes (with the exception of weird
edge cases with the padding attribute) already use sizes divisible by 4
anyway, and the common attribute header fields have a natural alignment
of 4. This means file contents will also have a minimum alignment
guarantee of 4 -- files requiring a larger guarantee can still be added
with the --alignment flag as usual.

In a rare placement edge case when adding a file with alignment
requirements, cbfstool may need to generate a CBFS header that's
slightly larger than it needs to be. The way we do this is by just
increasing the data offset field in the CBFS header until the data falls
to the desired value.
This approach works but it may confuse parsing code in the presence of
CBFS attributes. Normally, the whole area between the attribute offset
and the data offset is filled with valid attributes written back to
back, but when this header expansion occurs the attributes are followed
by some garbage data (usually 0xff). Parsers are resilient against this
but may show unexpected error messages.
This patch solves the problem by moving the attribute offset forwards
together with the data offset, so that the total area used for
attributes doesn't change. Instead, the filename field becomes the
expanded area, which is a closer match to how this worked when it was
originally implemented (before attributes existed) and is less confusing
for parsers since filenames are zero-terminated anyway.

The *location argument to parse_elf_to_stage() is a relic from code all
the way back to 2009 where this function was still used to parse XIP
stages. Nowadays we have a separate parse_elf_to_xip_stage() for that,
so there is no need to heed XIP concerns here. Having a pointer to
represent the location in flash is absolutely irrelevant to a non-XIP
stage, and it is used incorrectly -- we just get lucky that no code path
in cbfstool can currently lead to that value being anything other than
0, otherwise the adjustment of data_start to be no lower than *location
could easily screw things up. This patch removes it.

Memlayout is a mechanism to define memory areas outside the normal
program segment constructed by the linker. Therefore, it generally
doesn't make sense to relocate memlayout symbols when the program is
relocated. They tend to refer to things that are always in one specific
spot, independent of where the program is loaded.
This hasn't really hurt us in the past because the use case we have for
rmodules (ramstage on x86) just happens to not really need to refer to
any memlayout-defined areas at the moment. But that use case may come up
in the future so it's still worth fixing.
This patch declares all memlayout-defined symbols as ABSOLUTE() in the
linker, which is then reflected in the symbol table of the generated
ELF. We can then use that distinction to have rmodtool skip them when
generating the relocation table for an rmodule. (Also rearrange rmodtool
a little to make the primary string table more easily accessible to the
rest of the code, so we can refer to symbol names in debug output.)
A similar problem can come up with userspace unit tests, but we cannot
modify the userspace relocation toolchain (and for unfortunate
historical reasons, it tries to relocate even absolute symbols). We'll
just disable PIC and make those binaries fully static to avoid that
issue.
