[PATCH 0/2] fixes for binutils 2.21

[Víctor Manuel Jáquez Leal]

These patches focus the same problem: with the binutils upgrade to
2.21 it is required specify the +sec to the march parameter.

The kernel patch is just grabbed from the ubuntu's repository. For the
u-boot I just came up with a translation of those patches.

[PATCH 1/2] u-boot-sakoman: fix break caused by the new binutils

[Víctor Manuel Jáquez Leal]

New assemblers need -march=armv7-a+sec on command line or .arch_extension sec
inline to enable use of the smc instruction.

This patch adds as-instr to check the latter to conditionally enable the
former in AFLAGS for files that use smc.

[PATCH 2/2] linux-omap4: fix break caused by the new binutils

[Víctor Manuel Jáquez Leal]

According to this discussion [1], a couple patches where required by the
kernel using the latest binutils (2.21).

This patch add those patches, which were posted in the Ubuntu's kernel
repository.

http://www.sakoman.com/cgi-bin/gitweb.cgi?p=u-boot.git;a=commitdiff;h=2a9a9da5530f5bc9cb09ffa2fe8e32494d1a8b0f

and 

http://www.sakoman.com/cgi-bin/gitweb.cgi?p=u-boot.git;a=commitdiff;h=268fff79ea11b2bb6f174c3c97c104768b5cd7e3

So, I'm not sure what should I do. Any advise?
