Debug installing Fedora with RAID partitions

I'm trying to install Fedora onto a pair of 250GB hard drives with either RAID0 or RAID1.

Debug logging

The issue seems to be the following from journal.txt:

Dec 05 21:27:51 server anaconda[1647]: program: Installing for i386-pc platform.
Dec 05 21:27:51 server anaconda[1647]: program: grub2-install: warning: ../grub-core/partmap/gpt.c:190:this GPT partition label contains no BIOS Boot Partition; embedding won't be possible.
Dec 05 21:27:51 server anaconda[1647]: program: grub2-install: error: embedding is not possible, but this is required for RAID and LVM install.

Boot into Linux on a Chromebook

The best resource for Chrome hardware is https://mrchromebox.tech/#devmode.

It seems like getting to a shell in order to install alternate firmware requires having ChromeOS installed. It is possible to create USB flash installation media using the following script and list of devices:

I didn't trust running the script with super user privileges so I ran dd manually as follows:

U-Boot patch to exit userspace tools when an invalid CRC is found
From 6482180e602c4853e43d5c5a40b3349b63aba276 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/1] env: Exit tools when invalid CRC found
fw_setenv and fw_printenv currently print a warning and use a default
environment compiled into the binary when an invalid CRC is found. This
modifies the default behavior to print an error and exit. This is
especially important when calling the tools from a script since the
script depends on the exit code of the tool to know something went

Enabling EEPROM support in U-Boot

Selecting CONFIG_SYS_I2C_ZYNQ and CONFIG_ZYNQ_I2C0 builds successfully (see Xilinx documentation). But those are old config options and should be replaced with CONFIG_I2C_CADENCE.

Selecting CONFIG_ENV_IS_IN_EEPROM causes the following assertion to fail:

cmd/eeprom.c:58:2: error: #error CONFIG_SYS_I2C_EEPROM_ADDR_LEN must be 1 or 2
 #error CONFIG_SYS_I2C_EEPROM_ADDR_LEN must be 1 or 2
