[U-Boot] [PATCH V3 00/06] Go to common initdram() on 85xx-based boards
This patch series consists of a bunch of cleanups that allow us to use a common initdram() on all of the non-corenet 85xx-based boards. Also, switch to using phys_size_t to represent the size of memory returned.
Most of these patches are just code rearranges or renaming things to get a common scheme in place. There are also lots of cleanups - the various initdram() implementations had a variety of issues that I have hopefully fixed.
This is a large patch series, and I've had to hack on a bunch of different boards that I know nothing about, so I'd appreciate any review commentary. I have tested this on 8572DS and confirmed that the results of a MAKEALL powerpc are the same before and after this series.
Changes from V1: - Removed prints from initdram() as suggested by Peter - Changed spacing of 36-bit DRAM size warning messages to better line up after the removal of the excess prints from initdram() - Switched sdram_init() to be a weak function - renamed sdram_init() to lbc_sdram_init()
Changes from V2: - dropped boards that Kumar is removing - changed spacing of printouts from lbc_sdram_init - added the "DDR:" back to the boot messages - it makes sense to have this for some boards, and it's not much clutter - renamed the DDR_WIMGE define per feedback
Diffstat below.
Cheers, Becly

Also, change this code to use phys_size_t instead of long int. Using common naming for this function will enable us to use the common initdram() for 85xx going forward. Other than the type change, this is just a code rearrange.

Some platforms might want to override the default wimge=0 for DDR. Add CONFIG_SYS_PPC_DDR_WIMGE for those platforms to use. This will initially only be used by TQM85xx, but could be useful for other boards or testing going forward. Note that the name of this define is not 85xx-specific. WIMGE is a fairly universal concept, so any ppc platforms that require different WIMGE settings for DDR can use the same #define.

Correct initdram to use phys_size_t to represent the size of dram; instead of changing this all over the place, and correcting all the other random errors I've noticed, create a common initdram that is used by all non-corenet 85xx parts. Most of the initdram() functions were identical, with 2 common differences:
1) DDR tlbs for the fixed_sdram case were set up in initdram() on some boards, and were part of the tlb_table on others. I have changed them all over to the initdram() method - we shouldn't be accessing dram before this point so they don't need to be done sooner, and this seems cleaner.
2) Parts that require the DDR11 erratum workaround had different implementations - I have adopted the version from the Freescale errata document. It also looks like some of the versions were buggy, and, depending on timing, could have resulted in the DDR controller being disabled. This seems bad.
The xpedite boards had a common/fsl_8xxx_ddr.c; with this change only the 517 board uses this so I have moved the ddr code into that board's directory in xpedite517x.c
The ATUM8548 board didn't appear to set up any tlbs in the fixed_sdram case; this patch fixes that.

Add spaces to cause the informational prints to line up with the ones from init_func_ram() in board.c. Output now looks like this:
.... DRAM: Detected 4096 MB of memory This U-Boot only supports < 4G of DDR You could rebuild it with CONFIG_PHYS_64BIT DDR: 2 GiB (DDR2, 64-bit, CL=5, ECC off) ....
The prints from lbc_sdram_init() have also been modified to line line up and changed to start with "LBC SDRAM" instead of the confusing "SDRAM".

- Parts that require the DDR11 erratum workaround had different
implementations - I have adopted the version from the Freescale errata document. It also looks like some of the versions were buggy, and, depending on timing, could have resulted in the DDR controller being disabled. This seems bad.
The xpedite boards had a common/fsl_8xxx_ddr.c; with this change only the 517 board uses this so I have moved the ddr code into that board's directory in xpedite517x.c
The ATUM8548 board didn't appear to set up any tlbs in the fixed_sdram case; this patch fixes that.

Some platforms might want to override the default wimge=0 for DDR. Add CONFIG_SYS_PPC_DDR_WIMGE for those platforms to use. This will initially only be used by TQM85xx, but could be useful for other boards or testing going forward. Note that the name of this define is not 85xx-specific. WIMGE is a fairly universal concept, so any ppc platforms that require different WIMGE settings for DDR can use the same #define.
