This feature can be used to trigger special command "sysrstcmd" using
reset key long press event and environment variable "sysrstdelay" is set
(useful for reset to factory or manufacturing mode execution)
Kirkwood SoC implements a hardware-based SYSRSTn duration counter.
When SYSRSTn is asserted low, a SYSRSTn duration counter is running.
The counter value is stored in the SYSRSTn Length Counter Register
The counter is based on the 25-MHz reference clock (40ns)
It is a 29-bit counter, yielding a maximum counting duration of
2^29/25 MHz (21.4 seconds). When the counter reach its maximum value,
it remains at this value until counter reset is triggered by setting
bit 31 of KW_REG_SYSRST_CNT
Implementation:
Upon long reset assertion (> ${sysrstdelay} in secs) sysrstcmd will be
executed if pre-defined in environment variables.
This feature will be disabled if "sysrstdelay" variable is unset.
for-ex.
setenv sysrst_cmd "echo starting factory reset;
nand erase 0xa0000 0x20000;
echo finish ed sysrst command;"
will erase particular nand sector if triggered by this event

The MPIC initialization code for Freescale e500 CPUs was not using I/O
accessors, and it was not issuing a read-back to the MPIC after setting
mixed mode. This may be the cause of a spurious interrupt on some systems.

P1020 is another member of QorIQ series of processors which falls in ULE
category. It is an e500 based dual core SOC.
Being a scaled down version of P2020 it has following differences:
- 533MHz - 800MHz core frequency.
- 256Kbyte L2 cache
- Ethernet controllers with classification capabilities.
Also the SOC is pin compatible with P2020

The number of CPUs are getting detected dynamically by checking the
processor SVR value. Also removed CONFIG_NUM_CPUS references from all
the platforms with 85xx/86xx processors.
This can help to use the same u-boot image across the platforms.
Also revamped and corrected few Freescale Copyright messages.

For historic reasons we had defined some additional PLATFORM_CPPFLAGS like:
PLATFORM_CPPFLAGS += -DCONFIG_MPC86xx=1
PLATFORM_CPPFLAGS += -DCONFIG_MPC8641=1
However these are all captured in the config.h and thus redudant. Also
moved common 86xx flags into cpu/mpc86xx/config.mk.

For some time there have been repeated reports about build problems
with some ARM (cross) tool chains. Especially issues about
(in)compatibility with the tool chain provided runtime support
library libgcc.a caused to add and support a private implementation
of such runtime support code in U-Boot. A closer look at the code
indicated that some of these issues are actually home-made. This
patch attempts to clean up some of the most obvious problems and make
building of U-Boot with different tool chains easier:
- Even though all ARM systems basicy used the same compiler options
to select a specific ABI from the tool chain, the code for this was
distributed over all cpu/*/config.mk files. We move this one level
up into lib_arm/config.mk instead.
- So far, we only checked if "-mapcs-32" was supported by the tool
chain; if yes, this was used, if not, "-mabi=apcs-gnu" was
selected, no matter if the tool chain actually understood this
option. There was no support for EABI conformant tool chains.
This patch implements the following logic:
1) If the tool chain supports
"-mabi=aapcs-linux -mno-thumb-interwork"
we use these options (EABI conformant tool chain).
2) Otherwise, we check first if
"-mapcs-32"
is supported, and then check for
"-mabi=apcs-gnu"
If one test succeeds, we use the first found option.
3) In case 2), we also test if "-mno-thumb-interwork", and use
this if the test succeeds. [For "-mabi=aapcs-linux" we set
"-mno-thumb-interwork" mandatorily.]
This way we use a similar logic for the compile options as the
Linux kernel does.
- Some EABI conformant tool chains cause external references to
utility functions like raise(); such functions are provided in the
new file lib_arm/eabi_compat.c
Note that lib_arm/config.mk gets parsed several times, so we must
make sure to add eabi_compat.o only once to the linker list.

When we init the addrmap based on the TLB we will not end up getting
the TLB that covers memory if we are using SPD. The reason is we
haven't relocated at the point that we setup the memory TLB and thus it
will not get setup in the addrmap.
Instead we can just walk over the TLB array after we've relocated and
see all the TLBs that have been set and use that information to populate
the initial addrmap. By doing this we insure that we get the TLB
entries that cover memory.

It was brought to our attention that U-Boot contains code derived from the
IBM OpenBIOS source code originally provided with some of the older PowerPC
4xx development boards. As a result, the original license of this code has
been carried in the various files for a number of years in the U-Boot project.
IBM is dual-licensing the IBM code contributions already present in U-Boot
under either the terms of the GNU General Public License version 2, or the
original code license already present.

For some reason the AT91rm9200 lowlevel init writes to a bunch of
reserved or read-only addresses. All the boards seem to define the
value-to-be-written values as zero ... but they shouldn't actually
be writing *anything* there.
No documented erratum justifies these accesses. It looks like maybe
some pre-release BDI-2000 setup code has been carried along by cargo
cult programming since at least late 2004 (per GIT history).
Here's a patch disabling what seems to be bogosity. Tested on a
csb337; there were no behavioral changes.

Commit 70ebf316 factored out the ROUND() macro into include/common.h,
not realizing that the primary use of this macro on AT91 systems was
in start.S where common.h was not included, and could not be included
because it contains a lot of C code which the assembler doesn't
understand.
This patch wraps such code in common.h in a "#ifndef __ASSEMBLY__"
construct, and then adds an include to cpu/arm926ejs/start.S thus
solving the problem.

This patch adds support for the AVR32 LCD controller. This patch is
based off the latest u-boot-video.
A quick summary of what's going on:-
Enable LCDC pixel clock
Enable LCDC port pins
Add framebuffer pointer to global_data struct
Allocate framebuffer
To use the new code, update your board config to include something like
this:-
#define CONFIG_LCD 1
#if defined(CONFIG_LCD)
#define CONFIG_CMD_BMP
#define CONFIG_ATMEL_LCD 1
#define LCD_BPP LCD_COLOR16
#define CONFIG_BMP_16BPP 1
#define CONFIG_FB_ADDR 0x10600000
#define CONFIG_WHITE_ON_BLACK 1
#define CONFIG_VIDEO_BMP_GZIP 1
#define CONFIG_SYS_VIDEO_LOGO_MAX_SIZE 262144
#define CONFIG_ATMEL_LCD_BGR555 1
#define CONFIG_SYS_CONSOLE_IS_IN_ENV 1
#define CONFIG_SPLASH_SCREEN 1
#endif
The standard U-Boot BMP and Splash-screen features should just work.

This patch adds a generic command for programming I2C bootstrap
eeproms on PPC4xx. An implementation for Canyonlands board is
included.
The command name is intentionally chosen not to be PPC4xx specific.
This way other CPU's/SoC's can implement a similar command under
the same name, perhaps with a different syntax.
Usage on Canyonlands:
=> chip_config
Available configurations (I2C address 0x52):
600-nor - NOR CPU: 600 PLB: 200 OPB: 100 EBC: 100
600-nand - NAND CPU: 600 PLB: 200 OPB: 100 EBC: 100
800-nor - NOR CPU: 800 PLB: 200 OPB: 100 EBC: 100
800-nand - NAND CPU: 800 PLB: 200 OPB: 100 EBC: 100
1000-nor - NOR CPU:1000 PLB: 200 OPB: 100 EBC: 100
1000-nand - NAND CPU:1000 PLB: 200 OPB: 100 EBC: 100
1066-nor - NOR CPU:1066 PLB: 266 OPB: 88 EBC: 88 ***
1066-nand - NAND CPU:1066 PLB: 266 OPB: 88 EBC: 88
=> chip_config 600-nor
Using configuration:
600-nor - NOR CPU: 600 PLB: 200 OPB: 100 EBC: 100
done (dump via 'i2c md 52 0.1 10')

as well.

Patch d873133f [ppc4xx: Add Sequoia RAM-booting target] broke "normal"
booting on some 44x platforms. This breakage is only noticed in some
cases while powercycling. As it seems, the code in question in start.S
didn't invalidate TLB #0. This makes sense since this TLB is used for
the bootrom mapping. With the patch mentioned above even TLB #0 got
invalidated resulting in an error later on.
This patch now fixes this issue by only invalidating TLB #0 in the RAM-
booting case.
Tested succesfully on Sequoia and Canyonlands.
