74xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cache
The patch is following the commit 392438406041415fe64ab8748ec5ab5ad01d1cf7 mpc86xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cache This is needed in unlock_ram_in_cache() because it is called from C and will corrupt the small data area anchor that is kept in R2. lock_ram_in_cache() is modified similarly as good coding practice, but is not called from C. Signed-off-by: Nick Spence <nick.spence@freescale.com> also, the r2 is used as global data pointer. Signed-off-by: Dave Liu <daveliu@freescale.com>
