Hi Nick,

Thanks for the update.  A few questions/observations:

1. I think the third mask on 'elf32_thumb2_plt_entry[1]' when applying
   the constants should be '0x08000000' instead of '0x08000800'.

2. Why do we limit the offset to 24 bits?  It seems the encoding allows
   for a full 32 bits, e.g. a fourth line that does:

     | ((got_displacement & 0xf0000000) >> 28)


   I understand why the 'elf32_arm_plt_entry' has this limitation.
