Some U-Boot pointers have redundant information, so we can use a scheme where we can return either an error code or a pointer with the same return value. The default implementation just casts the pointer to a number, however, this may fail on platforms where the end of the address range is used for valid pointers (e.g. 0xffffff00 is a valid heap pointer in socfpga SPL). For such platforms, this value provides an upper range of those error pointer values - up to 'MAX_ERRNO' bytes below this value must be unused/invalid addresses.
