[U-Boot] Maximum size of u-boot.imx for TBS2910 board

[Heinrich Schuchardt]

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.

Best regards

Heinrich
