8a87a3d72e omap3: Introduce weak misc_init_r
Introduce a __weak misc_init_r function that just runs dieid_num_r().
Remove misc_init_r from cm_t35, mcx, omap3_logic and mt_ventoux as this was
all they did for misc_init_r.

f2ae6c1a83 OMAP4: scale voltage of core before MPU scales
OMAP4 requires that parent domains scale ahead of dependent domains.
This is due to the restrictions in timing closure. To ensure
a consistent behavior across all OMAP4 SoC, ensure that
vdd_core scale first, then vdd_mpu and finally vdd_iva.

As part of doing this refactor the logic to allow for future
addition of OMAP4470 without much ado. OMAP4470 uses different
SMPS addresses and cannot be introduced in the current code
without major rewrite.

3acb553439 OMAP4460: TPS Ensure SET1 is selected after voltage configuration
TPS SET0/SET1 register is selected by a GPIO pin on OMAP4460 platforms.
Currently we control this pin with a mux configuration as part of
boot sequence.
Current configuration results in the following voltage waveform:
                           |---------------| (SET1 default 1.4V)
                           |               --------(programmed voltage)
                           | <- (This switch happens on mux7,pullup)
vdd_mpu(TPS)         -----/ (OPP boot voltage)
                                             --------- (programmed voltage)
vdd_core(TWL6030)    -----------------------/ (OPP boot voltage)
Problem 1)                |<----- Tx ------>|
   timing violation for a duration Tx close to few milliseconds.
Problem 2) voltage of MPU goes beyond spec for even the highest of MPU OPP.

By using GPIO as recommended as standard procedure by TI, the sequence
changes to:
                                  -------- (programmed voltage)
vdd_mpu(TPS)         ------------/ (Opp boot voltage)
                                   --------- (programmed voltage)
vdd_core(TWL6030)    -------------/ (OPP boot voltage)

a78274b205 OMAP3+: Introduce generic logic for OMAP voltage controller
OMAP Voltage controller is used to generically talk to
PMICs on OMAP3,4,5 over I2C_SR. Instead of replicating code
in multiple SoC code, introduce a common voltage controller
logic which can be re-used from elsewhere.

With this change, we replace setup_sri2c with omap_vc_init which
has the same functionality, and replace the voltage scale
replication in do_scale_vcore and do_scale_tps62361 with
omap_vc_bypass_send_value. omap_vc_bypass_send_value can also
now be used with any configuration of PMIC.

NOTE: Voltage controller controlling I2C_SR is a write-only data
path, so no register read operation can be implemented.

67ee3dd35e mx53: Make PLL2 to be the parent of UART clock
Change the parent UART clock to be PLL2, so that U-boot can also boot
a Freescale 2.6.35 kernel for mx53.

FSL kernel and U-boot changed the UART parent from PLL3 to PLL2 to avoid
conflicts with IPU clocks, so that the video resolution can be changed
without affecting the UART clock.

On a 2.6.35 kernel the serial console is messed up after IPU driver is loaded
and this patch fixes this problem.

Tested on a mx53loco board booting a FSL kernel and also a mainline kernel.

f1f2c3ca9f armv7: omap3: leave outer cache enabled

Leaving L2$ enabled can be troublesome in cases where

Cortex-A9. This problem is explained in detail in
the commit dc7100f408

However, this problem doesn't apply to Cortex-A8
because L2$ in Cortex-A8 is under CP15 control and
hence the generic armv7 maintenance opertions work
for it.

As such we can make an exception for OMAP3 and
leave the L2$ enabled when we jump to kernel. This
is done by removing the strongly-linked implementation
of v7_outer_cache_disable() and allowing it to fall
back to the weakly linked implementation that doesn't
do anything.

Tegra appears to boot with function UARTA pre-selected on mux

it's unclear which group's pins drive the RX signals into the

practice. To solve this, configure some alternative function on
SDB to avoid the conflict. Also, tri-state the group to avoid
driving any signal onto it until we know what's connected.

initialization code amd other related dead code.

80433c9ac6 arm: Move CP15 init out of cpu_init_crit()
Some SOCs have do not start up with their 'main' CPU. The first U-Boot
code may then be executed with a CPU which does not have a CP15, or not a
useful one.

Here we split the initialization of CP15 into a separate call, which can
be performed later if required.

Once the main CPU is running, you should call cpu_init_cp15() to perform
this init as early as possible.

Existing ARMv7 boards which define CONFIG_SKIP_LOWLEVEL_INIT should not
need to change, this CP15 init is still skipped in that case. The only
impact for these boards is that the cpu_init_cp15() will be available
even if it is never used on these boards.

210576fc5e tegra2: Simplify tegra_start() boot path
The Tegra2 boot path is more complicated than it needs to be. Since we want
to move to building most of U-Boot with ARMv7 and only a small part with
ARMv4T (for AVP) it should be as simple as possible.

This makes tegra2_start() into a simple function which either does AVP
init or A9 init depending on which core is running it. Both cores now
following the same init path, beginning at _start, and the special Tegra2
boot path code is no longer required.

Only two files need to be built for ARMv4T, and this is handled in the
Tegra2 CPU Makefile.

e43d6ed932 tegra2: Add arch_cpu_init() to fire up Cortex-A9
We want to move away from a special Tegra2 start-up, and just use
arch_cpu_init() instead. However, if we run board_init_f() from boot
we need to build it for ARMv4T, since the Tegra's AVP start-up CPU
does not support ARMv7.

The effect of this is to do the AVP init earlier, and in
arch_cpu_init(), rather that board_early_init_f().
