arm64: zynqmp: Switch all platforms to DM_I2C · 8bdad433

CONFIG_PCA953X is not needed because of PCA953X is integrated in gpio
subsystem already. That's why also remove CMD_PCA953X which is only for
this driver.

zcu102/zcu104-revC/zcu106/zcu111 contain links to eeprom which stores MAC address.

DM_I2C is not enabled for the whole SoC because it increase size for
mini configurations and there is no I2C symbol present to setup

arm64: versal: Define distro boot commnads for qspi ospi and mmc · a318b939

Siva Durga Prasad Paladugu authored Jan 31, 2019



This patch adds distro boot commands for qspi, ospi and mmc.
The distro boot commands now reads the script from flash offset
of 63.5MB  for qspi and ospi and executes it. For mmc its same
as generic distro boot command. As either one of the qspi or ospi can
exist on hardware, defined a single distroboot command as xspi
that works for both.

Setup default location via script_offset_f to 63.5MB to match the most
xilinx reference boards for qspi, ospi for now.
512kB allocated space for script size (script_size_f) should be more
than enough to cover custom boot logic.

Heinrich ran into issues with HII and iPXE which lead to #SErrors on
his Odroid-C2 system. We definitely do not want to regress just yet,
so let's not expose the HII protocols by default.

Instead, let's make it a config option that people can play with
This way, we can stabilize the code in tree without breaking any
users.

Once someone figures out, why this breaks iPXE (probably a NULL
dereference), we can enable it by default.
