Automatically build the 'u-boot.imx' (i.e. imx header + u-boot.bin) and 'SPL'
(i.e. imx header + u-boot-spl.bin) make targets for all imx processors
supporting this header, so for arm926ejs, arm1136 and armv7. Some combinations
were missing.
At the same time, fix the build of SPL targets not supporting the imx header on

In the case of booting from certain peripherals, such as UART, we must
not see what the device descriptor says for RAW or FAT mode because in
addition to being nonsensical, it leads to a hang. This is why we have
a test currently for the boot mode being within range. The problem
however is that on some platforms we get MMC2_2 as the boot mode and not
the defined value for MMC2, and in others we get the value for MMC2_2.
This is required to fix eMMC booting on omap5_uevm.
Tested on am335x_evm (UART, NAND, SD), omap3_beagle (NAND, SD on

Commit "8602114 omap: emif: configure emif only when required"
breaks SDRAM_AUTO_DETECTION.
The issue is dmm_init() depends on emif_sizes[](SDRAM Auto detection)
done in do_sdram_init(). The above commit moves dmm_init() above
do_sdram_init() because of which dmm_init() uses uninitialized
emif_sizes[].

Some small fixes in the exynos pwm driver:
1. NS_IN_HZ is non-sensical since these are not compatible units. This
constant actually describes the number of nanoseconds in a second. Renamed it
to NS_IN_SEC. Also dropped the unnecessary parenthesis.
2. The variable "period" is not used to hold a period, it's used to hold a
frequency. Renamed it to "frequency".
3. tcmp is an unsigned value, so (tcmp < 0) will never be true and the if
which checks that condition will never execute. Also, there should be no
problem if the pwm never switches, so there's no reason to subtract one from
tcmp and therefore no reason to compare it against zero. Removed both ifs. If
they weren't removed, tcmp should be a signed value.
4. Add a check for a 0 period.

First, the "div" value was being used incorrectly to compute the frequency of
the PWM timer. The value passed in is a constant which reflects the value
that would be found in a configuration register, 0 to 4. That should
correspond to a scaling factor of 1, 2, 4, 8, or 16, 1 << div, but div + 1 was
being used instead.
Second, the reset value of the timers were being calculated to give an overall
frequency, thrown out, and set to a maximum value. This was done so that PWM 4
could be used as the system clock by counting down from a high value, but it
was applied indiscriminantly. It should at most be applied only to PWM 4.
This change also takes the opportunity to tidy up the pwm_init function.

- On a mx6qsabresd revB:

Add workaround for the following ARM errata: 743622 and 751472.
The motivation for this change is the following kernel commit 62e4d357a
(ARM: 7609/1: disable errata work-arounds which access
secure registers), which removes the errata from multiplatform kernel.
Since imx has been converted to multiplatform in the kernel, we need to apply
such workarounds into the bootloader.
Workaround code has been taken from arch/arm/mm/proc-v7.S from 3.7.1 kernel.

been observed that, RTC clock need couple of seconds delay to stabilize

especially during early init and also it will impact quick/fast boot

Currently PLL2 is not explicitely configured for mx53 and it runs at 333MHz.
Since PLL2 is the parent clock for DDR2, IPU, VPU, we should set it at 400MHz
instead.
Without doing so, it is not possible to use a 2.6.35 FSL kernel and display HDMI
at 1080p because the IPU clock cannot reach the requested frequency.
Set PLL2 to 400MHz, so that 1080p can be played and the DDR2 can run at its
maximum frequency.
Also, setup the other PLL's as done in FSL U-boot and re-arrange the code a little
bit to allow easier comparison with the original clock setup from FSL U-boot.

Clean up the i.MX5 clock driver:
- Use readl() and writel() instead of their __raw_ counterparts.
- Use the clr/setbits_le32() family of macros rather than expanding code.
- Use accessor macros for bit-fields instead of _MASK and _OFFSET.

Add meaningful constants for each clock channels and use them for
enabling and disabling i.MX6 clocks.
Includes an update to enable/disable the IPU1 clock in
drivers/video/ipu_common to remove IMX5x register access
when used on i.MX6 as discussed in V1:

The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h.
Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs
that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20'
'root' file.
All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK.

Move files that are going to be common between T20 and T30 into 'tegra-common'
subdirs in AVP (arm720t), CPU (armv7), and shared (arch/arm/cpu/.) areas. Any
files that are left behind in '/tegra20' will be copied to '/tegra30' subdirs
and modified for that SoC. The 'common' files should need only minor changes.
Include files (arch/arm/include/asm/arch-tegra/tegra20) will be done in a
follow-on patch.
Builds fine w/MAKEALL -s tegra20. Checkpatch.pl is clean.

This adds the required code to set up a ULPI USB port. It is
mostly a port of the Linux ULPI setup code with some tweaks
added for more correctness, discovered along the way of
debugging this.
To use this both CONFIG_USB_ULPI and CONFIG_USB_ULPI_VIEWPORT
have to be set in the board configuration file.

Under option -munaligned-access, gcc can perform local char
or 16-bit array initializations using misaligned native
accesses which will throw a data abort exception. Fix files
where these array initializations were unneeded, and for
files known to contain such initializations, enforce gcc
option -mno-unaligned-access.

The restore sequence in lowlevel_init was in the wrong order,
causing lr to lose its original value and be set equal to ip
instead. Also, its use of the stack clashes with that of
s_init, so move the s_init call after the restore and turn
it into a tail-optimized branch.

lowlevel_init() of rmobile badly assumed that ip register holds return address.

This patch aims at ensuring that the 2012.10 release works
out-of-the-box on as many targets as possible, by reinstating
commit 5347560f5427bcdd48a563b62180481606ac8044, which adds
option -mno-unaligned-access to armv7 builds.
This patch will be overriden immediately after release of 2012.10.

Rmobile common timer driver diverts the same driver as SH architecture.
When it builds at the same place with source, it is no problem, but when
it builds out of source, it cannot build.
This patch revises this problem.
