[PATCH 0/2] ARM: at91: usb-a9g20: make it work out of the box again

[Wolfram Sang]

Here are the remaining two patches to make a (for me) useable barebox
with the defconfig and no other patches. Comments welcome!

[PATCH 1/2] ARM: at91: usb-a926x: remove nand partitions from config

[Wolfram Sang]

We define partitions as well in the board file. Leading to:

New partition nand0.at91bootstrap (0x00000000-0x0001ffff) on nand0 overlaps with partition at91bootstrap_raw (0x00000000-0x0001ffff), not creating it
cannot create nand0.at91bootstrap: Invalid argument
addpart: Invalid argument

So, remove it from the config file.

Or shall I rather remove it from the board file?

No, doing it in the board file is preferred.

[PATCH 2/2] defconfigs: usb-a9g20: update to a working version

[Wolfram Sang]

The defconfig needs to be updated to get a usable barebox:

We need bigger malloc because of the increasing kernel size, soft ECC so
NAND will work, ifup and relocatable for easier development. Fix the
prompt while here. Sadly, because of size restrictions, FAT, NFS, menus,
netconsole, and SHA1 have to go.
