Nico Huber 12faea3095 libpayload: Cache physical location of cb_table entries
In the presence of self-relocating payloads, it's safer to keep
physical addresses in `libsysinfo`. This updates all the references
to coreboot-table entries that are not consumed inside libpayload
code.

Nico Huber 5e0db58533 libpayload: Cache copy of `cb_framebuffer` struct
Our AArch64 code supports dynamic framebuffer allocation which
makes it necessary to change the framebuffer information during
runtime. Having a pointer inside `libsysinfo` made a mess of it
as the pointer would either refer to the original struct inside
the coreboot table or to a new struct inside payload space. The
latter would be unaffected by a relocation of the payload.

Instead of the pointer, we'll always keep a copy of the whole
struct, which can be altered on demand without affecting the
coreboot table. To align the `video/graphics` driver with the
console driver, we also replace `fbaddr` with a macro `FB` that
calls phys_to_virt().

Nico Huber 14adb7eaa9 libpayload: Cache physical cbmem console address
Same as with other consoles and drivers that cache an address
outside the payload (e.g. video/corebootfb), we should store the
physical address, so we can derive the virtual address on demand.
This makes it save to use the address across relocations.

As a first step in migrating `libsysinfo` to `uintptr_t`, we
also switch to the physical address there.

Fixes the default build of FILO, tested with Qemu/i440FX and Qemu/Q35.

Dan Ehrenberg 6addd40268 libpayload: Take flash parameters from coreboot
A payload may want to run erase operations on SPI NOR flash without
re-probing the device to get its properties. This patch passes up
three properties of flash to achieve that:
- The size of the flash device
- The sector size, i.e., the granularity of erase
- The command used for erase
The patch sends the parameters through coreboot and then libpayload.
The patch also includes a minor refactoring of the flash erase code.
Parameters are sent up for just one flash device. If multiple SPI
flash devices are probed, the second one will "win" and its
parameters will be sent up to the payload.

TEST=Observed parameters to be passed up to depthcharge through
libpayload and be used to correctly initialize flash and do an erase.
TEST=Winbond and Gigadevices spi flash drivers compile with the changes;
others don't, for seemingly unrelated reasons.

Vadim Bendebury 2a0f8cd41b libpayload: move MRC processing to x86 path and remove ACPI_GNVS duplication
It turns out that CB_TAG_ACPI_GNVS is handled in both x86 specific and
common coreboot table parsing code. The MRC cache case used only by
x86 is handled in the common code.

This patch restores sanity and moves processing to where it belongs.

BRANCH=none
BUG=none
TEST=verified that arm and x86 targets build.

Vadim Bendebury 864ec8c488 libpayload: Consolidate coreboot table parsing
There are three instances of coreboot.c in libpayload. for x86, arm
and arm64 architectures. The arm and arm64 instances are exactly the
same. The differences with the x86 instance are as follows:

 - a very slightly different set of coreboot table tags is parsed (one
   tag added and two removed)

 - instead of checking a fixed address if it contains the coreboot
   table, the x86 version iterates over two address ranges.

This patch refactors the module, leaving architecture specific
processing in arch subdirectories and moving the common code into
libc.
