arm/arm64: zynq/zynqmp: pass the PS init file as a kconfig variable U-Boot needs to link ps7_init_gpl.c on Zynq or psu_init_gpl.c on ZynqMP (PS init for short). The current logic to locate this file for both platforms is: 1. if a board-specific file exists in board/xilinx/zynq[mp]/$(CONFIG_DEFAULT_DEVICE_TREE)/ps?_init_gpl.c then use it 2. otherwise use board/xilinx/zynq/ps?_init_gpl.c In the latter case the file does not exist in the U-Boot sources and must be copied in the source tree from the outside before starting the build. This is typical when it is generated from Xilinx tools while developing a custom hardware. However making sure that a board-specific file is _not_ found (and used) requires some trickery such as removing or overwriting all PS init files (e.g.: the current meta-xilinx yocto layer). This generates a few problems: * if the source tree is shared among different out-of-tree builds, they will pollute (and potentially corrupt) each other * the source tree cannot be read-only * any buildsystem must add a command to copy the PS init file binary * overwriting or deleting files in the source tree is ugly as hell Simplify usage by allowing to pass the path to the desired PS init file in kconfig variable XILINX_PS_INIT_FILE. It can be an absolute path or relative to $(srctree). If the variable is set, the user-specified file will always be used without being copied around. If the the variable is left empty, for backward compatibility fall back to the old behaviour. Since the issue is the same for Zynq and ZynqMP, add one kconfig variable in a common place and use it for both. Also use the new kconfig help text to document all the ways to give U-Boot the PS init file. Build-tested with all combinations of: - platform: zynq or zynqmp - PS init file: from XILINX_PS_INIT_FILE (absolute, relative path, non-existing), in-tree board-specific, in board/xilinx/zynq[mp]/ - building in-tree, in subdir, in other directory Signed-off-by: Luca Ceresoli <luca@lucaceresoli.net> Cc: Albert Aribaud <albert.u.boot@aribaud.net> Cc: Michal Simek <michal.simek@xilinx.com> Cc: Nathan Rossi <nathan@nathanrossi.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>

config XILINX_PS_INIT_FILE
string "Zynq/ZynqMP PS init file(s) location"
help
On Zynq and ZynqMP U-Boot SPL (or U-Boot proper if
ZYNQMP_PSU_INIT_ENABLED is set) is responsible for some
basic initializations, such as enabling peripherals and
configuring pinmuxes. The PS init file (called
psu_init_gpl.c on ZynqMP, ps7_init_gpl.c for Zynq-7000)
contains the code for such initializations.
U-Boot contains PS init files for some boards, but each of
them describes only one specific configuration. Users of a
different board, or needing a different configuration, can
generate custom files using the Xilinx development tools.
There are three ways to give a PS init file to U-Boot:
1. Set this variable to the path, either relative to the
source tree or absolute, where the psu_init_gpl.c or
ps7_init_gpl.c file is located. U-Boot will build this
file.
2. If you leave an empty string here, U-Boot will use
board/xilinx/zynq/$(CONFIG_DEFAULT_DEVICE_TREE)/ps7_init_gpl.c
for Zynq-7000, or
board/xilinx/zynqmp/$(CONFIG_DEFAULT_DEVICE_TREE)/psu_init_gpl.c
for ZynqMP.
3. If the above file does not exist, U-Boot will use
board/xilinx/zynq/ps7_init_gpl.c for Zynq-7000, or
board/xilinx/zynqmp/psu_init_gpl.c for ZynqMP. This file
is not provided by U-Boot, you have to copy it there
before the build.

The patch enables changing this address which is necessary for cases where default address is pointing to location (DDR) which is not present. The access to this location can cause exception.

board: xilinx: Add support for user configurable boot script offset Currently "script_offset_f" env variable is hardcoded, this variable specifies from which offset of the flash boot.scr should be read/write. As flashes are of different sizes having a fixed offset makes it difficult to load other images into the flash which may overwrite the boot script or cannot utilize the full memory. This current fix creates a new config "CONFIG_BOOT_SCRIPT_OFFSET" which holds the offset address, overwrites the "script_offset_f" variable.

xilinx: cmd: Add support for FRU commands This patch adds support for fru commands "fru capture" and "fru display". The fru capture parses the FRU table present at an address and stores in a structure for later use. The fru display prints the content of captured structured in a readable format. As of now, it supports only common header and board area of FRU. Also, it supports only English language code and ASCII8/BINARY formats. fru_data variable is placed to data section because fru parser can be called very early before bss is initialized. And also information needs to be shared that's why it is exported via header.
