b012bc94ac x86: Add console command to display CBMEM console buffer
This command is useful to allow to observe messages generated by
coreboot and u-boot until present. In particular it is handy when
u-boot is instrumented to fall through into console mode on startup
errors.

98ab435f73 x86: Add CBMEM console driver for coreboot
This patch builds upon the recently introduced CBMEM console
feature of coreboot.

CBMEM console uses a memry area allocated by coreboot to store
the console output. The memory area has a certain structure,
which allows to determine where the buffer is, the buffer size
and the location of the pointer in the buffer. This allows
different phases of the firmware (rom based coreboot, ram based
coreboot, u-boot after relocation with this change) to keep
adding text to the same buffer.

Note that this patch introduces a new console driver and adds the
driver to the list of drivers to be used for console output, i.e.
it engages only after u-boot relocates. Usiong CBMEM console for
capturing the pre-relocation console output will be done under a
separate change.

>From Linux, run the cbmem.py utility (which is a part of the coreboot
package) to see the output, e.g.:

vvvvvvvvvvvvvvvvv
SCSI:  AHCI 0001.0300 32 slots 6 ports ? Gbps 0xf impl SATA mode
flags: 64bit ilck stag led pmp pio
...
Magic signature found
Kernel command line: "cros_secure  quiet loglevel=1 console=tty2...
^^^^^^^^^^^^^^^^^

Note that the entire u-boot output fits into the buffer only if
the coreboot log level is reduced from the most verbose. Ether
the buffer size will have to be increased, or the coreboot
verbosity permanently reduced.

8bc50f0b6d powerpc/mpc8xxx: move LAW code into arch/powerpc/cpu/mpc8xxx
It's arch code and not a driver, so move it where it belongs.  When it
originally went into drivers/misc there was no 8xxx CPU directory.

This will make new-SPL support a little easier since we can keep the CPU
stuff together and not need to pull stuff in from drivers/misc.

c733681507 pmic: Extend PMIC framework to support multiple instances of PMIC devices
The PMIC framework has been extended to support multiple instances of
the variety of devices responsible for power management.
This change allows supporting of e.g. fuel gauge, charger, MUIC (Micro USB
Interface Circuit).
Power related includes have been moved to ./include/power directory.
This is a first of a series of patches - in the future "pmic" will be
replaced with "power".

Two important issues:
1. The PMIC needs to be initialized just after malloc is configured
2. It uses list to hold information about available PMIC devices

461632bd71 powerpc/corenet_ds: Slave module for boot from PCIE
When boot from PCIE, slave's core should be in holdoff after powered on for
some specific requirements. Master will release the slave's core at the
right time by PCIE interface.

Slave's ucode and ENV can be stored in master's memory space, then slave
can fetch them through PCIE interface. For the corenet platform, ucode is
for Fman.

NOTE: Because the slave can not erase, write master's NOR flash by
	  PCIE interface, so it can not modify the ENV parameters stored
	  in master's NOR flash using "saveenv" or other commands.

environment and requirement:

master:
	1. NOR flash for its own u-boot image, ucode and ENV space.
	2. Slave's u-boot image is in master NOR flash.
	3. Put the slave's ucode and ENV into it's own memory space.
	4. Normally boot from local NOR flash.
	5. Configure PCIE system if needed.
slave:
	1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV.
	2. Boot location should be set to one PCIE interface by RCW.
	3. RCW should configure the SerDes, PCIE interfaces correctly.
	4. Must set all the cores in holdoff by RCW.
	5. Must be powered on before master's boot.

For the slave module, need to finish these processes:
	1. Set the boot location to one PCIE interface by RCW.
    2. Set a specific TLB entry for the boot process.
	3. Set a LAW entry with the TargetID of one PCIE for the boot.
	4. Set a specific TLB entry in order to fetch ucode and ENV from
	   master.
	5. Set a LAW entry with the TargetID one of the PCIE ports for
	   ucode and ENV.
	6. Slave's u-boot image should be generated specifically by
	   make xxxx_SRIO_PCIE_BOOT_config.
	   This will set SYS_TEXT_BASE=0xFFF80000 and other configurations.

In addition, the processes are very similar between boot from SRIO and
boot from PCIE. Some configurations like the address spaces can be set to
the same. So the module of boot from PCIE was added based on the existing
module of boot from SRIO, and the following changes were needed:
	1. Updated the README.srio-boot-corenet to add descriptions about
	   boot from PCIE, and change the name to
	   README.srio-pcie-boot-corenet.
	2. Changed the compile config "xxxx_SRIOBOOT_SLAVE" to
	   "xxxx_SRIO_PCIE_BOOT", and the image builded with
	   "xxxx_SRIO_PCIE_BOOT" can support both the boot from SRIO and
	   from PCIE.
	3. Updated other macros and documents if needed to add information
	   about boot from PCIE.

81fa73bab0 powerpc/corenet_ds: Get rid of the CONFIG_SRIOBOOT_SLAVE_PORTx macro
When compile the slave image for boot from SRIO, no longer need to
specify which SRIO port it will boot from. The code will get this
information from RCW and then finishes corresponding configurations.

This has the following advantages:
	1. No longer need to rebuild an image when change the SRIO port for
	   boot from SRIO, just rewrite the new RCW with selected port,
	   then the code will get the port information by reading new RCW.
	2. It will be easier to support other boot location options, for
	   example, boot from PCIE.

6d8962e814 Switch from archive libraries to partial linking
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.

2f721d1733 MXC: Fix byte-ordering in SPI driver for i.MX31/i.MX51
The actual SPI driver for i.MX31 and i.MX51 controller
use a wrong byte ordering, because it is supposed
to work only with Freescale's devices, as the Power
Controllers (PMIC). The driver is not suitable for
general purposes, because the buffers passed to spi_xfer
must be 32-bit aligned, as it is used mainly to send
integer to PMIC devices.

The patch drops any kind of limitation and makes the
driver useful with devices controlled sending commands
composed by single bytes (or by a odd number of bytes), such as
spi flash, sensor, etc.

Because the byte ordering is changed,
any current driver using this controller must be adapted, too.

54841ab50c Make sure that argv[] argument pointers are not modified.
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) {

ead39d7aa3 TWL4030: make LEDs selectable for twl4030_led_init()
Not all boards have both LEDs hooked, so enabling both on
boards with single LED will just waste power. Make it
possible to choose LEDs by adding argument to
twl4030_led_init().

Using this turn on only LEDB for pandora, leave both LEDs
on for all other boards, as it was before this patch.

418ec85843 ppc/p4080: Add support for CoreNet style platform LAWs
On CoreNet based platforms the LAW address is split between an high &
low register and we no longer shift the address.  Also, the target IDs
on CoreNet platforms have been completely re-assigned.

Additionally, added a new find_law() API to which LAW an address hits in.
This is need for the CoreNet style boot release code since it will need
to determine what the target ID should be set to for boot window
translation.

Finally, enamed LAWAR_EN to LAW_EN and moved to header so we can use
it elsewhere.
