Hi Philipp:
Sorry for the late reply, we just come back from the Chinese Spring
Festival.

Kever,
Independent of whether we revert this for the current cycle (and also
independent of
if I ever find the other patch you had been referring to — I couldn’t
find it in my local
mailing list archive) and then deprecate it for the next release
(unless converted to
DM), we still have a number of architectural issues that need to be
addressed:
I still doubt is this a right work-flow for patch apply. Before we
apply a patch which will break many other boards , should we make
sure there is a solution patch applied for these boars first?
1.This really should be a driver under DTS control.
2.We need to not get away from configuring SOM-specific addresses via
Kconfig
Both these issues are technical debt that we’ve accumulated over the
last 18 months
and need to address for the sake of future maintainability.
E.g. ‘setting an address to 0x0 via Kconfig to disable a
driver/feature’ really isn’t in line
with the architectural direction of U-Boot.
For technical side, I think CONFIG_ROCKCHIP_BOOT_MODE_REG is necessary
here, we will read this register from save_boot_params when we get out
from bootrom, the dtb is not available at this point.
On the other hand, almost rockchip based products use a recovery key to
enter download(upgrade)mode, this is a muti-funtion key, most of them
reuse with vol+- key, we would like the u-boot share
dtb with linux kernel. To keep the linux kernel dts as clean as possible
,we don't want to add another dts property to describe this key either.
This is why I implement function rockchip_dnl_key_pressed as __weak.
I don’t have my own house completely in order (I’ve been talking for a
year now about
finally wrapping the RGMII/GMII selection into an ioctl-call to a
driver) yet, but that doesn’t
mean that we we should delay this clean-up more than absolutely necessary.
Thanks,
Philipp.

Hi Philipp,
This is not right, this patch should not merged like this!!!
I have give my review comment in previous mail, and this will break
many boards.
My another patch do not break anything, but you insist NAK it
without acceptable reason;
What other patch?
I don’t remember seeing that one...
This patch definitely break other board and I have comment it, but
you just ignore other people's review and merge it, good job!
Thanks,

This function causes a 5-second delay and stops the display working on
minnie. This code should be in a driver and should only be enabled by
a device-tree property, so that it does not affect devices which
do not
have this feature.
