coreboot sets up CLK_PM, ASPM, and L1ss automatically based on related
bits in "Link Capability Register" and "L1 PM Substates Capabilities
Register". coreboot overrides these configs even if the driver sets
them. Therefore, setting up CLK_PM, ASPM, and L1ss in the driver is
redundant and useless.

coreboot sets up certain configs (e.g. L1ss) based on the device's
reported capacities; however, this BayHub lv2 driver modifies some
of its capacities after coreboot uses them. Therefore, coreboot may
make incorrect configs based on out-of-date capacities.
This patch moves the driver from ".init" to ".enable" so that the
capacities are set before the rest of coreboot queries them.

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

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.
