At the moment arch/arm/boards/eukrea_cpuimx51/lowlevel_init.S and
./arch/arm/boards/freescale-mx51-pdk/lowlevel_init.S are exact copies.
What is being done first in board_init_lowlevel is
- workaround the errata
- configure aux control reg
- dis/enable L2 cache
This is basically the same as being done in mx53_init_lowlevel().
Can we instead add a mx5_init_lowlevel which contains the L2 cache
setting and is called from both mx51_init_lowlevel and mx53_lowlevel?
