Re: [U-Boot] [PATCH 3/3] arm: socfpga: gen5: fix ERR_PTR_OFFSET

The default implementation of ERR_PTR/PTR_ERR maps errno values at the and of the address range (e.g. -EINVAL/-22 gets 0xFFFFFFEA).

For socfpga gen5 SPL, this doesn't really work, as the heap is nearly at the end of the 32 bit address range.

This patch adjusts the ERR_PTR_OFFSET to map errno values into the range of the Boot ROM, which should not be used for valid pointers.

Applied to u-boot/master, thanks!
