There is no reason to have ZYNQ specific Kconfig macro in generic location to be visible for all other SoCs. That's why move it to Xilinx common location to be visible only for us. Also introduce new bool entry ZYNQ_MAC_IN_EEPROM to have also an option to disable it or enable. This has connection to code which is reading the whole content of i2c and also work with the rest of date not just with MAC address. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

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.
