2022-05-13util/amdfwtool: Add amdfwread utilityRobert Zieba
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 Signed-off-by: Robert Zieba <robertzieba@google.com> Change-Id: I15fa07c9cad8e4640e9c40e5539b0dab44424850 Reviewed-on: https://review.coreboot.org/c/coreboot/+/62795 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Rob Barnes <robbarnes@google.com>

2022-04-25amdfwtool: Use command line option use-combo to decide if use comboZheng Bao
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.

2022-04-25amdfwtool: Change the name of macros for 'BHD'Zheng Bao
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.

2022-04-14util/amdfwtool: Maintain one copy of PSP Level2 entriesKarthikeyan Ramasubramanian
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.

2021-12-16amdfwtool: Upgrade "relative address" to four address modesZheng Bao
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.
