Currently, 83xx, 86xx, and 85xx have a lot of duplicated code
dedicated to defining and manipulating the LBC registers. Merge
this into a single spot.
To do this, we have to decide on a common name for the data structure
that holds the lbc registers - it will now be known as fsl_lbc_t, and we
adopt a common name for the immap layouts that include the lbc - this was
previously known as either im_lbc or lbus; use the former.
In addition, create accessors for the BR/OR regs that use in/out_be32
and use those instead of the mismash of access methods currently in play.
I have done a successful ppc build all and tested a board or two from
each processor family.

The various boards that have PIXIS FPGAs have slightly different
register definitions, however there is some common functionality (like
reset, ICS307 clk control, etc) that can be shared.
The struct definition exists for MPC8536DS, MPC8544DS, MPC8572DS,
MPC8610HPCD, and MPC8641HPCN boards.
Also fixed ngpixis to be __packed__ instead of aligned.

This patch provides support for MPC8308RDB development board from
Freescale with a minimal set of features:
Dual UART is supported
NOR flash is supported
Both TSEC Ethernet controllers are supported
PCI Express initialization is supported
The following features are enabled in configuration but not fully tested:
I2C (used to get the board revision)
I2C-connected RTC
VSC7385 switch
There is one (hopefully) minor issue: on soft reset the board sometimes
resets twice. I've not managed to find the fix for this problem yet.
As a workaround instruction cache can be disabled.

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 (--argc > 0 && **++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 == '-') {
char *arg = *argv;
while (*++arg) {
switch (*arg) {

On the MPC85xx platform if we have SATA its connected on SERDES.
Determing if SATA is enabled via sata_initialize should not be board

Additionally, now that we have is_serdes_configured() we can determine
if the given SATA port is enabled and error out if its not in the
driver.

The Freescale P2020DS board uses a new type of PIXIS FPGA, called the ngPIXIS.
The ngPIXIS has one distinct new feature: the values of the on-board switches
can be selectively overridden with shadow registers. This feature is used to
boot from a different NOR flash bank, instead of having a register dedicated
for this purpose. Because the ngPIXIS is so different from the previous PIXIS,
a new file is introduced: ngpixis.c.
Also update the P2020DS checkboard() function to use the new macros defined
in the header file.

Refactor and document the Freescale PIXIS code, used on most 85xx and 86xx
boards. This makes the code easier to read and more flexible.
Delete pixis.h, because none of the exported functions were actually being
used by any other file. Make all of the functions in pixis.c 'static'.
Remove "#include pixis.h" from every file that has it.
Remove some unnecessary #includes.
Make 'pixis_base' into a macro, so that we don't need to define it in every
function.
Add "while(1);" loops at the end of functions that reset the board, so that
execution doesn't continue while the reset is in progress.
Replace in_8/out_8 calls with clrbits_8, setbits_8, or clrsetbits_8, where
appropriate.
Replace ulong/uint with their spelled-out equivalents. Remove unnecessary
typecasts, changing the types of some variables if necessary.
Add CONFIG_SYS_PIXIS_VCFGEN0_ENABLE and CONFIG_SYS_PIXIS_VBOOT_ENABLE to make
it easier for specific boards to support variations in the PIXIS registers
sets. No current boards appears to need this feature.

After determining how much DDR is actually in the system, set DBAT0 and
IBAT0 accordingly. This ensures that the CPU won't attempt to access
(via speculation) addresses outside of actual memory.
On 86xx systems, DBAT0 and IBAT0 (the BATs for DDR) are initialized to 2GB
and kept that way. If the system has less than 2GB of memory (typical for
an MPC8610 HPCD), the CPU may attempt to access this memory during
speculation. The zlib code is notorious for generating such memory reads,
and indeed on the MPC8610, uncompressing the Linux kernel causes a machine
check (without this patch).
Currently we are limited to power of two sized DDR since we only use a
single bat. If a non-power of two size is used that is less than
CONFIG_MAX_MEM_MAPPED u-boot will crash.
