svn commit: r295420 - head/sys/boot/efi/loader/arch/arm

[Andrew Turner]

Author: andrew

New Revision: 295420
URL: https://svnweb.freebsd.org/changeset/base/295420

Log:
  Ensure the bss is aligned to a 4-byte address as we use 4-byte aligned
  stores to clear it.
  
  While here reduce the alignment of the data from 4k to 16 byte aligned.
  This should be more than enough, without wasting too much space.
