* ppc4xx: Move ppc4xx headers to powerpc include directoryStefan Roese2010-09-23-1/+1
| | | | | | | | | This patch moves some ppc4xx related headers from the common include directory (include/) to the powerpc specific one (arch/powerpc/include/asm/). This way to common include directory is not so cluttered with files. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Add SDRAM detection for PMC440 boardsMatthias Fuchs2009-10-02-24/+58
| | | | | | | | | | | | This patch adds support to detect the amount of DDR2 SDRAM on PMC440 modules. Detection is done by probing through a list of available and supported hardware configurations from 1GByte down to 256MB. The static TLB entry is replaced by dynamically created entries.

* ppc4xx: PMC440: Only use one CS (rank) in DDR2 configurationStefan Roese2009-03-17-1/+1
| | | | | | | | | This patch fixes a problem spotted by Mikhail Zolotaryov on Sequoia with the DDR2 configuration to only use one CS (rank). As this code is most likely copied from the original Sequoia version, this error was copied as well. Signed-off-by: Stefan Roese <sr@denx.de>

* Change initdram() return type to phys_size_tBecky Bruce2008-06-12-1/+1
| | | | | | | | | | | | | | | | | | | This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code. Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc MPC8641HPCN. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>

* ppc4xx: Add initial esd PMC440 board filesMatthias Fuchs2007-12-28-0/+442
This patch adds the first files for the new esd PMC440 boards. The next two patches will complete the PMC440 board support. Signed-off-by: Matthias Fuchs <matthias.fuchs@esd-electronics.com>
