Robert Zieba 29bc79fddb util/amdfwtool: Add amdfwread utility
Amdfwtool creates AMD firmware images however there is currently no way
to get information from an existing image. This commit adds amdfwread to
support that functionality. At the moment only reading PSP soft fuse
flags is supported. Example usage: `amdfwread --soft-fuse bios.bin`,
example output: `Soft-fuse:0x400000030000041`.

BUG=b:202397678
TEST=Ran amdfwread and verified that it correctly reads the soft fuse
bits, verified that built AMD FW still boots on DUT

Zheng Bao 993b43f2be amdfwtool: Use command line option use-combo to decide if use combo
The macro PSP_COMBO is removed and instead use the flag use_combo. As
long as this flag is false, the amdfwtool behaves the same way as the
macro does.

Zheng Bao 96a3371a72 amdfwtool: Change the name of macros for 'BHD'
Use BHD instead of BDT as the name of cookie macro. Use L2 to make it
clear it is for level 2. The 'BHD2' is misleading, which is going to
be used for combo entry. The definition in psp_verstage is also changed.

Karthikeyan Ramasubramanian ad06bae7b1 util/amdfwtool: Maintain one copy of PSP Level2 entries
AMDFWtool maintains 2 copies of PSP Level2 entries - one in primary slot
A (Type 0x48) and another in backup slot B (Type 0x4A). On boards which
use VBOOT with 2 RW firmware slots, maintaining 2 copies of PSP Level2
entries in each FW slot is redundant and space-consuming. Introduce
option to maintain only one copy of PSP Level2 entries and point to it
from both slots A & B.

BUG=None
TEST=Build and boot to OS in Skyrim. Ensure that only one copy is added
to each FW slot. This achieved a space saving of 1.5 MB in each FW slot.

Zheng Bao 990d154898 amdfwtool: Add support for AMD's BIOS A/B recovery feature
The rom layout for A/B recovery:
EFS -> PSP L1 0x48 -> PSP L2 A -> BIOS L2 A
              0x4A -> PSP L2 B -> BIOS L2 B

The coreboot doesn't implement the AMD's A/B recovery. This is only
for the ROM layout. To save some flash space, the entire B section can
be eliminated.

To enable A/B recovery in PSP layout, add "--recovery-ab" to
amdfwtool.

Zheng Bao 6fff2497b1 amdfwtool: Upgrade "relative address" to four address modes
Address Mode 0: Physical Address, bit 63~56: 0x00
Address Mode 1: Relative Address to entire BIOS image, bit 63~56: 0x40
Address Mode 2: Relative Address to PSP/BIOS directory, bit 63~56: 0x80
Address Mode 3: Relative Address to slot N, bit 63~56: 0xC0

It is the expanding mode for simple relative address mode, for which
address_mode equals 1.

Only mode 2 is added. We need to record current table base address and
calculate the offset. The ctx.current_table is zero outside the
table. When it goes into the function to integrate the table, it
should backup the old value and get current table base. Before it goes
out the function, it should restore the value.

If the table address mode is 2, the address in each entry should be
also add address mode information. If not, the address mode in entry
is meanless.

The old mode 0,1 should be back compatible.
