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.

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) {

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.

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.

eSDHC is mutually exlusive with UART0 (in 4-bits mode) and I2C2
(in 1-bit mode). When eSDHC is used, we should switch u-boot console to
UART1, and make the proper device-tree fixups.
Because of an erratum in prototype boards it is impossible to use eSDHC
without disabling UART0 (which makes it quite easy to 'brick' the board
by simply issung 'setenv hwconfig esdhc', and not able to interact with
U-Boot anylonger).
So, but default we assume that the board is a prototype, which is a most

U-Boot image from the memory device that interfaced to the controller,
such as the SDCard or SPI EEPROM, to the target memory, e.g. SDRAM or
L2SRAM, then boot from it.
The memory device should contain a specific data structure with control
word and config word at the fixed address. The config word direct the
process how to config the memory device, and the control word direct
the processor where to find the image on the memory device, or where
copy the main image to. The user can use any method to store the data
structure to the memory device, only if store it on the assigned address.
The on-chip ROM code will map the whole 4GB address space by setting
entry0 in the TLB1, so the main image need to switch to Address space 1
to disable this mapping and map the address space again.
This patch implements loading the mian U-Boot image into L2SRAM, so
the image can configure the system memory by using SPD EEPROM.

MPC8536E can support booting from NAND flash which uses the
image u-boot-nand.bin. This image contains two parts: a 4K
NAND loader and a main U-Boot image. The former is appended
to the latter to produce u-boot-nand.bin. The 4K NAND loader
includes the corresponding nand_spl directory, along with the
code twisted by CONFIG_NAND_SPL. The main U-Boot image just
like a general U-Boot image except the parts that included by
CONFIG_SYS_RAMBOOT.
When power on, eLBC will automatically load from bank 0 the
4K NAND loader into the FCM buffer RAM where CPU can execute
the boot code directly. In the first stage, the NAND loader
copies itself to RAM or L2SRAM to free up the FCM buffer RAM,
then loads the main image from NAND flash to RAM or L2SRAM
and boot from it.
This patch implements the NAND loader to load the main image
into L2SRAM, so the main image can configure the RAM by using
SPD EEPROM. In the first stage, the NAND loader copies itself
to the second to last 4K address space, and uses the last 4K
address space as the initial RAM for stack.
Obviously, the size of L2SRAM shouldn't be less than the size
of the image used. If so, the workaround is to generate another
image that includes the code to configure the RAM by SPD and
load it to L2SRAM first, then relocate the main image to RAM
to boot up.

The "mac id" command took a 4-character parameter as the identifier string.
However, for any given board, only one kind of identifier is acceptable, so it
makes no sense to ask the user to type it in. Instead, if the user enters
"mac id", the identifier (and also the version, if it's NXID) will
automatically be set to the correct value.
Improve the message that is displayed when EEPROM is read during boot. It now
displays "EEPROM:" and then either an error message or the EEPROM identifier
if successful.
If the identifier in EEPROM is valid, then always reject a bad CRC, even if the
CRC field has not been initialized.
Don't force the MAC address count to MAX_NUM_PORTS or less. Forcing the value
to be changed resulting in an in-memory copy that does not match what's in
hardware, even though the user did not request that change.
Finally, always update the CRC value in the in-memory copy after any field
is changed, so that the CRC is always correct.

A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
which needs to be added the the linker script. Instead of just adding this
one section, we use a wildcard ".rodata*" to get all rodata linker section
gcc has now and might add in the future.
However, '*(.rodata*)' by itself will result in sub-optimal section
ordering. The sections will be sorted by object file, which causes extra
padding between the unaligned rodata.str.1.1 of one object file and the
aligned rodata of the next object file. This is easy to fix by using the
SORT_BY_ALIGNMENT command.
This patch has not be tested one most of the boards modified. Some boards
have a linker script that looks something like this:
*(.text)
. = ALIGN(16);
*(.rodata)
*(.rodata.str1.4)
*(.eh_frame)
I change this to:
*(.text)
. = ALIGN(16);
*(.eh_frame)
*(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))
This means the start of rodata will no longer be 16 bytes aligned.
However, the boundary between text and rodata/eh_frame is still aligned to
16 bytes, which is what I think the real purpose of the ALIGN call is.

Clean up PCI mapping concepts in the 8641 config - rename _BASE
to _BUS, as it's actually a PCI bus address, separate virtual
and physical addresses into _VIRT and _PHYS, and use each
appopriately.

Because the inbound pci windows are mapped generously, set up
the more specific outbound windows first. This way, when we
search the pci regions for something, we will hit on the more
specific region. This can actually be a problem on systems
with large amounts of RAM.

The PCI_REGION_MEMORY and PCI_REGION_MEM are a bit to similar and
can be confusing when reading the code.
Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY to clarify its used
for system memory mapping purposes.

Remove command name from all command "usage" fields and update
common/command.c to display "name - usage" instead of
just "usage". Also remove newlines from command usage fields.

The diufb command usage formatting is non-standard. It was
made standard in preparation for larger command usage updates.

Rather than have the board code initialize SATA automatically during boot,
make the user manually run "sata init". This brings the SATA subsystem in
line with common U-Boot policy.
Rather than having a dedicated weak function "is_sata_supported", people
can override sata_initialize() to do their weird board stuff. Then they
can call the actual __sata_initialize().

For light loaded system, we use the 1T timing to gain better
memory performance, but for some heavily loaded system,
you have to add the 2T timing options to board files.

Introduce a new define to seperate out the virtual address that PCI
IO space is at from the physical address. In most situations these are
mapped 1:1. However any code accessing the bus should use VIRT.
