Subject: arm: Enable SYS_THUMB_BUILD on AT91
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=a9a73799731807cca117d234c4338b710db3cfdd;p=u-boot.git

arm: Enable SYS_THUMB_BUILD on AT91

Several AT91 boards are quite close to their SPL size limit. For example,
sama5d27_wlsom1_ek_mmc is just 173 bytes short of its limit and doesn't
even fit with older GCCs.

All AT91 processors should have thumb support. Enable SYS_THUMB_BUILD. This
shrinks SPL by around 30%.
