This patch adds the "ecctest" command to test and simulate ECC errors
(single bit and/or double bit) while running from SDRAM. Currently only
the IBM DDR2 controller is supported (405EX, 440SP(e), 460EX/GT).
This is done by copying and calling functions, modifying the SDRAM
controller operation mode, in internal SRAM/OCM.
For correctable ECC errors (single bit) only the status will be printed
since the DDR2 controller doesn't provide the faulting address:
=> ecctest 1000000 1
Using address 01000000 for 1 bit ECC error injection
ECC: Correctable error
Uncorrectable ECC errors (double bit) will also display the faulting
address:
=> ecctest 1000000 2
Using address 01000000 for 2 bit ECC error injection
ECC: Uncorrectable error at 0x0001000000
To enable this "ecctest" function you need to define CONFIG_CMD_ECCTEST
in the board config header.
Tested on katmai and t3corp.

The hush shell dynamically allocates (and re-allocates) memory for the
argument strings in the "char *argv[]" argument vector passed to
commands. Any code that modifies these pointers will cause serious
corruption of the malloc data structures and crash U-Boot, so make
sure the compiler can check that no such modifications are being done
by changing the code into "char * const argv[]".
This modification is the result of debugging a strange crash caused
after adding a new command, which used the following argument
processing code which has been working perfectly fine in all Unix
systems since version 6 - but not so in U-Boot:
int main (int argc, char **argv)

/* ====> */ while (*++*argv) {
switch (**argv) {
case 'd':
debug++;
break;
...
default:
usage ();
}
}
}
...
}
The line marked "====>" will corrupt the malloc data structures and
usually cause U-Boot to crash when the next command gets executed by
the shell. With the modification, the compiler will prevent this with
an
error: increment of read-only location '*argv'
N.B.: The code above can be trivially rewritten like this:
while (--argc > 0 && **++argv == '-') {

Background Info:
Some PPC440/460 boards have caches enabled in the Boot/FLASH TLB (via
init.S) to speed up the boot process. In relocate_code (start.S) the
cache inhibit attribute for this TLB is set to disable cache. This is
needed for the CFI FLASH driver.
This patch now cleans this code up:
- CONFIG_SYS_TLB_FOR_BOOT_FLASH is defined to 0 (default TLB) if not
defined in the top of this file. This way, we can remove an ugly
#ifdef in this code.
- Replace complex "#if defined(CONFIG_440EP) || defined(CONFIG_GR)..."
statement with "#if defined(CONFIG_440)".
- Remove unnecessary cache invalidate calls resulting in faster bootup.

This commit implements a workaround at least for the most blatant
problem: using memcpy() from NOR flash. We rename the assembler
routine into __memcpy() and provide a wrapper, which will use a
byte-wise copy loop for unaligned source or target addresses when
reading from NOR flash, and branch to the optimized __memcpy()
in all other cases, thus minimizing the performance impact.

also tested on these boards (albeit with a less accurate
boottime measurement method):
seconds: before after
8349MDS ~2.6 ~2.2
8360MDS ~2.8 ~2.6
8313RDB ~2.5 ~2.3 #nand boot
837xRDB ~3.1 ~2.3
also tested on an 8323ERDB.
v2: also remove the delayed icache enablement assumption in arch ppc's
board.c, and add a CONFIG_MPC83xx define in the ITX config file for
consistency (even though it was already being defined in 83xx'
config.mk).

marketing didn't extend their postpend-with-an-A naming strategy
on rev.2's and higher beyond the first two 83xx families. This
patch stops us from misreporting we're running e.g., on an MPC8313EA,
when such a name doesn't exist.

Enable eSDHC Clock based on generic CONFIG_FSL_ESDHC define
instead of a platform define. This will enable all the 83xx
platforms to use sdhc_clk based on CONFIG_FSL_ESDHC. It's
the same patch as commit 6b9ea08c50
for the ppc/85xx.

As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.
Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.
