The L2 size detection code was a bit confusing and we kept having to add
code to it to handle new processors. Change the sense of detection so we
look for the older processors that aren't changing.
Also added support for 1M cache size on 8572.

Some boards that have external 16550 UARTs don't have a direct
tie between bi_busfreq and the clock used for the UARTs. Boards
that do have such a tie should set CFG_NS16550_CLK to be
get_bus_freq(0) -- which most of them do already.

With a page size of BOOKE_PAGESZ_16M, both the real and effective
addresses must be multiples of 16MB. The hardware silently truncates
them so the code happens to work. This patch clarifies the situation
by establishing addresses that the hardware doesn't need to truncate.

This patch reworks the 440GX interrupt handling so that the common 4xx
code can be used. The 440GX is an exception to all other 4xx variants
by having the cascading interrupt vectors not on UIC0 but on a special
UIC named UICB0 (UIC Base 0). With this patch now, U-Boot references
the 440GX UICB0 when UIC0 is selected. And the common 4xx interrupt
handling is simpler without any 440GX special cases.
Also some additional cleanup to cpu/ppc4xx/interrupt.c is done.

This 2nd patch now removes all UIC mask bit definition. They should be
generated from the vectors by using the UIC_MASK() macro from now on.
This way only the vectors need to get defined for new PPC's.
Also only the really used interrupt vectors are now defined. This makes
definitions for new PPC versions easier and less error prone.
Another part of this patch is that the 4xx emac driver got a little
cleanup, since now the usage of the interrupts is clearer.

This patch is the first step to consolidate the UIC related defines in the

This patch completes the preprocessor mneomics for the IBM DDR2 SDRAM
controller registers (MODT and INITPLR) used by the
PowerPC405EX(r). The MMODE and MEMODE registers are unified with their
peer values used for the INITPLR MR and EMR registers,
respectively. Finally, a spelling typo is correct (MANUEL to MANUAL).
With these mnemonics in place, the CFG_SDRAM0_* magic numbers for
Kilauea are replaced by equivalent mnemonics to make it easier to
compare and contrast other 405EX(r)-based boards (e.g. during board
bring-up).
Finally, unified the SDRAM controller register dump routine such that
it can be used across all processor variants that utilize the IBM DDR2
SDRAM controller core. It produces output of the form:
PPC4xx IBM DDR2 Register Dump:
...
SDRAM_MB0CF[40] = 0x00006701
...
which is '<mnemonic>[<DCR #>] = <value>'. The DCR number is included
since it is not uncommon that the DCR values in header files get mixed
up and it helps to validate, at a glance, they match what is printed
in the user manual.
Tested on:
AMCC Kilauea/Haleakala:

Newer PPC's like 440SPe, 460EX/GT can be equipped with more than 2GB of SDRAM.
To support such configurations, we "only" map the first 2GB via the TLB's. We
need some free virtual address space for the remaining peripherals like, SoC
devices, FLASH etc.
Note that ECC is currently not supported on configurations with more than 2GB
SDRAM. This is because we only map the first 2GB on such systems, and therefore
the ECC parity byte of the remaining area can't be written.

The compiler will help find mismatches between printf formats and
arguments if you let it. This patch adds the necessary attributes to
declarations in include/common.h, then begins to correct the resulting
compiler warnings. Some of these were bugs, e.g., "$d" instead of
"%d" and incorrect arguments. Others were just annoying, like
int-long mismatches on a system where both are 32 bits. It's worth
fixing the annoying errors to catch the real ones.

This moves the MMC and SD Card command definitions from
include/asm/arch/mmc.h into include/mmc.h. These definitions are

During 83xx setup the "System I/O configuration register high" gets
overwritten with user defined value if CFG_SICRH is defined.
Regarding to the MPC834x manual (Table 5-28 reve.1) bits 28+29 of SICRH
must keep their reset value regardless of configuration.
On my board (using RGMII) those bits are set after reset - yet it's
unclear where they come from.
The patch keeps both bits on MPC834x and MPC8313.

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.

MPC8641HPCN.

The current cpu identification code is used just to return the name
of the processor at boot. There are some other locations that the name
is useful (device tree setup). Expose the functionality to other bits
of code.
Also, drop the 'E' suffix and add it on by looking at the SVR version
when we print this out. This is mainly to allow the most flexible use
of the name. The device tree code tends to not care about the 'E' suffix.
