xilinx: Free memory when variable is saved in boot_targets_setup()

2025-04-16T11:44:44+00:00

When boot_targets variable is saved there is no reason to keep string in
malloc area that's why free it. This change is already done in ZynqMP code.

xilinx: versal: remove versal loadpdi command

2025-04-16T11:44:44+00:00

The source code for the versal loadpdi command and the
CONFIG_CMD_VERSAL configuration has been removed. It now utilizes
the fpga load    command to load secure &
non-secure pdi images.

arm64: versal: fix dfu alt buffer clearing

2025-04-16T11:42:06+00:00

The set_dfu_alt_info() function calls the ALLOC_CACHE_ALIGN_BUFFER()
macro to declare a `buf' variable pointer into an array allocated on the
stack. It then calls the memset() function to clear the useable portion
of the array using the idiomatic expression `sizeof(buf)'.

While this would indeed work fine for an array, in the present case we
end up clearing only the size of a pointer.
Fix this by specifying the explicit size `DFU_ALT_BUF_LEN' instead.

xilinx: versal: add firmware access to PMC multi Boot mode register

2025-04-16T11:42:06+00:00

Added extended support for retrieving the PMC muti boot mode
register via the firmware interface, which is preferred when
U-Boot runs in EL2 and cannot directly access PMC registers
via raw reads. Ideally, all secure registers should be accessed
via xilinx_pm_request(). Introduced the secure
zynqmp_pm_get_pmc_multi_boot_reg() call, which uses
xilinx_pm_request() to read the PMC multi boot mode register.

BootROM increments the MultiBoot register (PMC_MULTI_BOOT) read
address offset by 32 KB and retries. For SD and eMMC boot modes,
it can search up to 8191 FAT files for the identification string.
A 13-bit mask (0x1FFF) is applied to PMC_MULTI_BOOT_MASK to obtain
the correct values in BootROM.

xilinx: versal: add firmware access to CRP Boot mode register

2025-04-16T11:42:06+00:00

Added extended support for retrieving the boot mode register
via the firmware interface, which is preferred when U-Boot
runs in EL2 and cannot directly access CRP registers via raw
reads. Ideally, all secure registers should be accessed via
xilinx_pm_request(). Introduced the secure zynqmp_pm_get_bootmode_reg()
call, which uses xilinx_pm_request() to read the boot mode register.

When CONFIG_ZYNQMP_FIRMWARE is enabled, the secure
zynqmp_pm_get_bootmode_reg() call is used; otherwise,
direct raw reads are performed in the case of mini U-Boot.

board: remove capsule update support in set_dfu_alt_info()

2025-04-11T11:20:37+00:00

Now that capsule update sets the dfu_alt_info environment variable
explicitly, there is no need to support it in the set_dfu_alt_info()
function. Decouple SET_DFU_ALT_INFO from EFI_CAPSULE_FIRMWARE_FIT and
EFI_CAPSULE_FIRMWARE_RAW. For many boards, this was the only use of
set_dfu_alt_info() so remove the function entirely.

arm64: versal: RO multi_boot register in non JTAG bootmode

2025-01-14T07:29:45+00:00

The main reason for this change is that upstream QEMU has no multiboot
register implemented that's why access to it fails which ends up in CI
failure for our target.
That's why in JTAG bootmode returns 0 which is correct behaviour because
multiboot register is not used in this mode and value should be ignored and
as a side effect it is also fixing CI/Qemu issue.

Also move versal_get_bootmode() to avoid function declaration.
