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) {
			...

0df01fd3d7 nios2: fix r15 issue for gcc4
The "-ffixed-r15" option doesn't work well for gcc4. Since we
don't use gp for small data with option "-G0", we can use gp
as global data pointer. This allows compiler to use r15. It

ecee9324d7 Program net device MAC addresses after initializing
Add a new function to the eth_device struct for programming a network
controller's hardware address.

After all network devices have been initialized and the proper MAC address
for each has been determined, make a device driver call to program the
address into the device.  Only device instances with valid unicast addresses
will be programmed.

4ba31ab33a Rewrite the miiphybb (Bit-banged MII bus driver) in order to support an arbitrary number of mii buses.
This feature is useful when your board uses different mii buses for different
phys and all (or a part) of these buses are implemented via bit-banging mode.

The driver requires that the following macros should be defined into the board
configuration file:

CONFIG_BITBANGMII       - Enable the miiphybb driver
CONFIG_BITBANGMII_MULTI - Enable the multi bus support

If the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needs
to define at least the following macros:

MII_INIT      - Generic code to enable the MII bus (optional)
MDIO_DECLARE  - Declaration needed to access to the MDIO pin (optional)
MDIO_ACTIVE   - Activate the MDIO pin as out pin
MDIO_TRISTATE - Activate the MDIO pin as input/tristate pin
MDIO_READ     - Read the MDIO pin
MDIO(v)       - Write v on the MDIO pin
MDC_DECLARE   - Declaration needed to access to the MDC pin (optional)
MDC(v)        - Write v on the MDC pin

The previous macros make the driver compatible with the previous version
(that didn't support the multi-bus).

When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill
the bb_miiphy_buses[] array with a record for each required bus and declare
the bb_miiphy_buses_num variable with the number of mii buses.
The record (struct bb_miiphy_bus) has the following fields/callbacks (see
miiphy.h for details):

char name[]            - The symbolic name that must be equal to the MII bus
                         registered name
int (*init)()          - Initialization function called at startup time (just
                         before the Ethernet initialization)
int (*mdio_active)()   - Activate the MDIO pin as output
int (*mdio_tristate)() - Activate the MDIO pin as input/tristate pin
int (*set_mdio)()      - Write the MDIO pin
int (*get_mdio)()      - Read the MDIO pin
int (*set_mdc)()       - Write the MDC pin
int (*delay)()         - Delay function
void *priv             - Private data used by board specific code

The board code will look like:

struct bb_miiphy_bus bb_miiphy_buses[] = {
 { .name = miibus#1, .init = b1_init, .mdio_active = b1_mdio_active, ... },
 { .name = miibus#2, .init = b2_init, .mdio_active = b2_mdio_active, ... },
 ...
int bb_miiphy_buses_num = sizeof(bb_miiphy_buses) /
                          sizeof(bb_miiphy_buses[0]);

dd9ca98f26 sbc8548: reclaim wasted sector in boot flash
By nature of being based off the MPC8548CDS board, this
board inherited an ENV_SIZE setting of 256k.  But since
it has a smaller flash device (8MB soldered on), it has
a native sector size of 128k, and hence the ENV_SIZE was
causing 2 sectors to be used for the environment.

By removing the unused sector, we can push TEXT_BASE up
closer to the end of address space and reclaim that
sector for any other application.  This also fixes the
mismatch between TEXT_BASE and MONITOR_LEN reported by
Kumar earlier.

Since this board also supports the ability to boot off
the 64MB SODIMM flash, this change is forward looking
with that in mind; i.e. the settings for MONITOR_LEN
and ENV_SIZE will work when the 512k sectors of the
SODIMM flash are used for alternate boot in the future.

c4db335c2e Blackfin: change global data register from P5 to P3
Since the Blackfin ABI favors higher scratch registers by default, use the
last scratch register (P3) for global data rather than the first (P5).
This allows the compiler's register allocator to use higher number scratch
P registers, which in turn better matches the Blackfin instruction set,
which reduces the size of U-Boot by more than 1024 bytes...

fe613cdd4e sbc8349: combine HRCW flash and u-boot image flash
Up to this point in time, the sbc8349 board was storing the u-boot

flash (0xff80_0000), and once close to the end of flash (0xfff8_0000)
for the actual image that got executed.

This moves the TEXT_BASE to be the beginning of flash, which makes
the second copy of the image redundant, and frees up the flash
from the end of the environment storage to the end of the flash
device itself.
