Subject: [PATCH v2 0/4] rockchip: Improve support for Bob chromebook and add support for Kevin
Date: Tue, 14 Dec 2021 01:15:23 +0300	[thread overview]
Message-ID: <20211213221528.43102-1-alpernebiyasak@gmail.com> (raw)

I have recently started testing booting U-Boot from SPI on my gru-kevin
(as opposed to chainloading it from vendor coreboot + depthcharge) and
brought it to a better working state based on an initial support patch
from Marty [1][2] and some follow-up work by Simon [3].

I tried to keep them as the git author when I took things from their
work, but squashing other changes into those and rewriting commit
messages makes things a bit weird in my opinion, especially for keeping
their signoff. Do tell me if there is a better way to that.

As the Kevin and Bob boards are very similar, I assumed the config and
devicetree changes will be appropriate for Bob as well, and applied them
to it first. I do not have a Bob, so could not test on one myself, but
Simon did test an earlier version of this and it appears to work [4].

Other useful things for these boards:
- Patch to fix a hang when usb controllers exit [5] (or [6])
- Series to support HS400ES mode as HS400 training fails [7]
- Hack to skip eMMC reinitialization so it keeps working [8]

Changes in v2:
- Drop unnecessary ifdef.
- Clarify commit message regarding 'values set in coreboot'.
- Rebase on u-boot/next, fixing conflict in board_debug_uart_init()
