The ngPIXIS is an FPGA used on the reference boards of most Freescale PowerPC
SOCs. Although programming the ngPIXIS is mostly standard on all boards that
have it, the P1022DS is unique in that the ngPIXIS needs to be programmed in
"indirect" mode whenever the video display (DIU) is active.
To support indirect mode, and to make it easier to support other quirks on
future reference boards, the low-level ngPIXIS functions are all marked as
weak, so that board-specific code can override any of them. We take advantage
of this feature on the P1022DS, so that we can properly reset the board when
the DIU is active.

The "mac id" command is used to initialize the EEPROM data to a specific
format, but it was not updating the CRC. This didn't cause any real
problems, because writing the data to the EEPROM will always update the
CRC anyway, but it did result in a bogus CRC warning.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

Freescale application note AN3638 describes an update to the NXID format,
which stores MAC addresses and related data on an on-board EEPROM. The new
version adds support for up to 23 MAC addresses, instead of just 8. Since
the initial implementation of NXID had a "0" in the 'version' field, this
new version is called "v1".
Boards that are shipped with EEPROMs in the NXID v1 format should define
CONFIG_SYS_I2C_EEPROM_NXID_1 instead of CONFIG_SYS_I2C_EEPROM_NXID.

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.
Also update the P2020DS checkboard() function to use the new macros defined

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.

When aligning malloc()ed screen_base, invalid offset was added.
This not only caused misaligned result (which did not cause hardware
misbehaviour), but - worse - caused screen_base + smem_len to
be out of malloc()ed space, which in turn caused breakage of
futher malloc()/free() operation.
This patch fixes screen_base alignment.
Also this patch makes memset() that cleans framebuffer to be executed
on first initialization of diu, not only on re-initialization. It looks
correct to clean the framebuffer instead of displaying random garbage;
I believe that was disabled only because that memset caused breakage
of malloc/free described above - which no longer happens with the fix

The 8544DS and 8572DS platforms support an optional SGMII riser card to
expose ethernet over an SGMII interface. Once the card is in, it is also
necessary to configure the board such that it uses the card, rather than
the on-board ethernet ports. This can either be done by flipping dip switches
on the motherboard, or by modifying registers in the pixis. Either way
requires a reboot.
This adds a command to allow users to choose which ports are routed through
the SGMII card, and which through the onboard ports. It also allows users
to revert to the current switch settings.
This code does not work on the 8572, as the PIXIS is different.
