| * CFI Driver: Fix "flash not ready" problemWolfgang Denk2008-10-31-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a problem on systems where the NOR flash is attached to a 64 bit bus. The toggle bit detection in flash_toggle() is based on the assumption that the same flash address is read twice without any other interjacent flash accesses. However, on 32 bit systems the function flash_read64() [as currently implemented] does not perform an atomic 64 bit read - instead, this is broken down into two 32 bit read accesses on addresses "addr" and "addr + 4". So instead of reading a 64 bit value twice from "addr", we see a sequence of 4 32 bit reads from "addr", "addr + 4", "addr", and "addr + 4". The consequence is that flash_toggle() fails to work. This patch implements a simple, but somewhat ugly solution, as it avoids the use of flash_read64() in this critical place (by breaking it down manually into 32 bit read operations) instead of rewriting flash_read64() such to perform atomic 64 bit reads as one could expect. However, such a rewrite would require the use of floating point load operations, which becomes pretty complex: save MSR; set Floating Point Enable bit in MSR; use "lfd" instruction to perform atomic 64 bit read; use "stfd" to store value to temporary variable on stack; load u64 value from temporary variable; restore saved MSR; return u64 value; The benefit-cost ratio of such an implementation was considered too bad to actually attempt this, especially as we can expect that such an implementation would not only have a bigger memory footprint but also cause a performance degradation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
