096ca838b5 ARMV7: OMAP3: Convert setup_auxcr() to pure asm
This function consists entirely of inline asm statements, so writing
it directly in a .S file is simpler. Additionally, the inline asm is
not safe as is, since registers are not guaranteed to be preserved
between asm() statements.

2984470746 ARMV7: OMAP3: Fix and clean up L2 cache enable/disable functions
On OMAP34xx ES1.0, the L2 enable bit can only be set in secure mode,
so an SMC call to the ROM monitor is required.  On later versions,
and on newer devices, this bit is banked and we can set it directly.

The code checked only the ES revision of the chip, and hence incorrectly
used the ROM call on ES1.0 versions of other devices.

This patch adds a check for chip family as well as revision, and also
removes some code duplication between the enable and disable functions.

b2b9169f0b ARMV7: OMAP3: Update CPU type detection for AM35XX/OMAP36XX/37XX
TI has added new processors to the OMAP3 family.  This patch enhances
the code in sysinfo.c to detect which family member is present.

0e7b62179f ARMV7: OMAP: Move syslib.c to omap-common since it can be shared by OMAP3 and OMAP4
The functions in syslib.c can be shared, so this patch moves it from
cpu/omap3 to cpu/omap-common

f70409aff3 ARMV7: S5P: separate the peripheral clocks
Because of peripheral devices can select clock sources,
separate the peripheral clocks. (pwm, uart and so on)
It just return the pclk at s5pc1xx SoC,
but s5pc210 SoC must be calculated by own clock register setting.

37168dab52 ARMV7: S5P: rename from s5pc1xx to s5p
Because of these are common files around s5p Socs, rename from s5pc1xx to s5p.
And getting cpu_id is SoC specific, so move to SoC's header file.

d93d0f0cfe S5P: Use accessor functions instead of SoC specific defines to access the base address
This patch is intended to prepare the other S5P SoC. (s5pc210)
If use SoC specific defines then can't share with other SoC.
So, make the accessor functions for access the base address by common way.

51b5870bdc MX51EVK: fix return value of get_timer_masked
get_timer_masked() should return current timestamp,
not current ticks from hardware register.

Tested on one custom board with NAND flash.
Without this patch, NAND write always TIMEOUT
because get_timer(0) return a big value.

This patch applies for u-boot-2010.06

674e0b217f ARMV7: Fix udelay for OMAP4
The OMAP4 x-load code sets gptimer1 clock source to 32Khz.  This isn't
acceptable for udelay.  This patch changes from gptimer1 to gptimer2,
which uses sys_clk at 38.4 Mhz.

f56348af5d ARM: Rename arch/arm/cpu/arm_cortexa8 to armv7
The purpose of this patch is to prepare for adding the OMAP4 architecture, which is Cortex A9

Cortex A8 and A9 both belong to the armv7 architecture, hence the name change.

The two architectures are similar enough that substantial code can be shared.
