* 85xx: Add basic e500mc core supportKumar Gala2008-10-24-0/+14
| | | | | | | | | | | Introduce CONFIG_E500MC to deal with the minor differences between e500v2 and e500mc. * Certain fields of HID0/1 don't exist anymore on e500mc * Cache line size is 64-bytes on e500mc * reset value of PIR is different Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* 85xx: Use CONFIG_SYS_CACHELINE_SIZE instead of magic numberKumar Gala2008-10-24-2/+2
| | | | | | | Using CONFIG_SYS_CACHELINE_SIZE instead of 31 means we can handle e500mc's 64-byte cacheline properly when it gets added. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* mpc83xx: serdes: add forgotten shifts for rfcksAnton Vorontsov2008-10-21-1/+1
| | | | | | | | | | The rfcks should be shifted by 28 bits left. We didn't notice the bug because we were using only 100MHz clocks (for which rfcks == 0). Though, for SGMII we'll need 125MHz clocks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At least some revisions of the 8313, and possibly other chips, do not wait for all pages of the initial 4K NAND region to be loaded before beginning execution; thus, we wait for it before branching out of the first NAND page.

| * | ppc4xx: PPC44x MQ initializationYuri Tikhonov2008-10-17-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Set the MQ Read Passing & MCIF Cycle limits to the recommended by AMCC values. This fixes the occasional 440SPe hard locking issues when the 440SPe's dedicated DMA engines are used (e.g. by the h/w accelerated RAID driver). Previously the appropriate initialization had been made in Linux, by the ppc440spe ADMA driver, which is wrong because modifying the MQ configuration registers after normal operation has begun is not supported and could have unpredictable results. Comment from Stefan: This patch doesn't change the resulting value of the MQ registers. It explicitly sets/clears all bits to the desired state which better documents the resulting register value instead of relying on pre-set default values.

| * ARM DaVinci: Fix broken HW ECC for large page NAND.Hugo Villeneuve2008-09-10-5/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on original patch by Bernard Blackham <bernard@largestprime.net> U-boot's HW ECC support for large page NAND on Davinci is completely broken. Some kernels, such as the 2.6.10 one supported by MontaVista for DaVinci, rely upon this broken behaviour as they share the same code for ECCs. In the existing scheme, error detection *might* work on large page, but error correction definitely does not. Small page ECC correction works, but the format is not compatible with the mainline git kernel. This patch adds ECC code that matches what is currently in the Davinci git repository (since NAND support was added in 2.6.24). This makes the ECC and OOB layout written by u-boot compatible with Linux for both small page and large page devices and fixes ECC correction for large page devices. The old behaviour can be restored by defining the macro CFG_DAVINCI_BROKEN_ECC, which is undefined by default.
