Hello Soeren,
when trying to add support for function key support in the USB keyboard
driver u-boot.imx for the TBS2910 surpassed the maximum size for u-boot.imx.

Do you remember why on the TBS2910 board this size is limited to
0x5fc00? Other i.MX6 boards like the Wandboard allow a much larger
u-boot.imx.
The limit is defined here:
include/configs/tbs2910.h:80:
#define CONFIG_BOARD_SIZE_LIMIT 392192 /* (CONFIG_ENV_OFFSET - 1024) */
Could the value CONFIG_ENV_OFFSET=0x60000 be enlarged?
Many i.MX6 defconfigs use CONFIG_ENV_OFFSET=0xC0000.
The nature of these boards (aimed at end users) means that we just do
not want to / cannot really move the stored environment. Thanks!
Another possibility would be to reduce the image size by using
CONFIG_REGEX=n which should be fine for a board with only one supported
network interface.
Best regards
Heinrich
