I have just sent patch to mailing list.

Some my comments:

MIPS has incompatible errno.h that's why I don't remove it - it is up to custodian.

NIOS, NIOS2, i386 don't have errno.h is asm folder -> this mean for me that they don't
need it. If yes, let me know.

Some archs define EDEADLOCK to 58 and some as EDEADLK. I looked at Linux kernel
and there is EDEADLK that's why I added this implementation is asm-generic.
#define EDEADLOCK 58 /* File locking deadlock error */
#define EDEADLOCK EDEADLK

Some arch defined these 5 macros below - they are not used in U-BOOT that's why I removed them.

/* Should never be seen by user programs */
#define ERESTARTSYS 512
#define ERESTARTNOINTR 513
#define ERESTARTNOHAND 514 /* restart if no handler.. */
#define ENOIOCTLCMD 515 /* No ioctl command */

#define _LAST_ERRNO 515

Please test this change carefully. If you have any problem let me know.

Thanks,
Michal
