* ppc4xx: Fix problem with ECC ordering for PPC4xx NDFC platformsStefan Roese2009-05-23-2/+2
| | | | | | | | | | | | | This patch now uses the correct ECC byte order (Smart Media - SMC) to be used on the 4xx NAND FLASH driver. Without this patch we have incompatible ECC byte ordering to the Linux kernel NDFC driver. Please note that we also have to enable CONFIG_MTD_NAND_ECC_SMC in drivers/mtd/nand/nand_ecc.c for correct operation. This is done with a seperate patch.

* ppc4xx: Move definition for PPC4xx NAND FLASH controller to headerStefan Roese2009-05-23-6/+3
| | | | | | | | | This patch moves the definition for the PPC4xx NAND FLASH controller (NDFC) CONFIG_NAND_NDFC into include/ppc4xx.h. This is needed for the upcoming fix for the ECC byte ordering of the NDFC driver. Signed-off-by: Stefan Roese <sr@denx.de> Acked-by: Scott Wood <scottwood@freescale.com>
* Blackfin: fix timer_init()/timer_reset()Graf Yang2009-05-19-2/+3
| | | | | | | | | | | | | The timer_init() function was not using the right csync instruction, nor was it doing it right after disabling the core timer. The timer_reset() function would reset the timestamp, but not the actual timer, so there was a common edge case where get_timer() return a jump of one timestamp (couple milliseconds) right after resetting. This caused many functions to improperly timeout right away. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* MPC8260: fixup device tree by property instead of pathWolfgang Denk2009-05-15-5/+6
| | | | | | | | | | | | | | | | | | | | cpu/mpc8260/cpu.c used to use do_fixup_by_path_u32() to update the clock frequencies in the device tree, using a CPU path "/cpus/OF_CPU", with OF_CPU beind defined in the board config file. However, this does not work when one board config file (here: MPC8260ADS.h) is intended to be used for several diffrent CPUs and therefor contains a generic definition like "cpu@0", as the device trees that will then be loaded will contain specific names like "PowerPC,8272@0". We switch to using do_fixup_by_prop_u32() instead, so we can search for device_type="cpu", as it is done in other architectures, too.

* AFEB9260 network fixSergey Lapin2009-05-13-1/+1
| | | | | | | | AFEB9260 uses PA10, PA11 for ETX2 and ETX3. Also, due to extarnal pull-up on IRQ line, Micrel PHY ID is 1 after reset sequence, not 0. Signed-off-by: Sergey Lapin <slapin@ossfans.org>
* Blackfin: avoid get_sclk() with early serial debugMike Frysinger2009-05-06-5/+5
| | | | | | | | When the clock functions were changed to use cached values (and thereby avoiding expensive math functions), early serial debug broke because the baud programming is called before external memory is available. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: fix booting with older bootroms (no EVT1)Mike Frysinger2009-05-06-1/+11
| | | | | | | | | | | When dropping jump block support, the assumption was that all bootroms supported entry point redirection via the EVT1 register. Unfortunately, this turned out to be incorrect for the oldest Blackfin parts (BF533-0.2 and older and BF561). No one really noticed earlier because these parts usually are booted by bypassing the bootrom entirely, and older BF533 parts are not supported at all (too many anomalies).

* Blackfin: recurse with early serial initcodeMike Frysinger2009-05-06-1/+1

Accesses to bank 2 will result in an error if the Column Address Width for bank 3 (EB3CAW ) is not set to be the same as that of bank 2. WORKAROUND: If using bank 2, make sure that banks 2 and 3 have the same column address width settings in the EBIU_SDBCTL register.
