commit 21144298 (power: twl6035: add palmas PMIC support)
introduced twl6035_i2c_[read|write]_u8
Then, commit dd23e59d (omap5: pbias ldo9 turn on)
introduced palmas_[read|write]_u8 for precisely the same access
function. TWL6035 belongs to the palmas family, so instead of having
an twl6035 API, we could use an generic palmas API instead.
To stay consistent with the function naming of twl4030,6030 accessors,
we use palmas_i2c_[read|write]_u8

Since TPS659038/TWL6035/TWL6037 all belong to palmas family of TI PMICs,
rename twl6035_mmc1_poweron_ldo by a more generic palmas_mmc1_poweron_ldo

Rename twl6035 to palmas to allow reuse across multiple current and
future platforms
As part of this change, change the CONFIG_TWL6035_POWER to
CONFIG_PALMAS_POWER and update usage of header file accordingly.

twl4030_pmrecv_vsel_cfg currently first sets up device group (effectively
enabling the supply), and only then sets vsel (selects voltage). This could
lead to wrong voltage for a short time, or even long time if second i2c
write fails.
Fix this by writing vsel first and device group after that. Also
introduce error checking to not enable the supply if we failed to set
the voltage, and start logging errors as power supply problems are
usually important.

MMC interfaces are specified to be 3.3V compatible with an operating
voltage range of 3.1V to 3.5V for SD cards. This change affects
hardware using TWL4030 (TPS6595x) PMICs and should improve the
reliability when communicating with marginally-spec'd MMC devices.
3.15V is the highest possible level for this chip. This patch
has been tested on a Gumstix Overo board.

1. ftpmu010.h: fix and add definitions
Enhanced for more features and asm related support
according to datasheet.
Note:
- FTPMU010_PDLLCR0_HCLKOUTDIS is "incorrect" in datasheet.
- FTPMU010_PDLLCR0_DLLFRANG is only 1 bit at bit #19. (not 20-19)
- FTPMU010_PDLLCR0_HCLKOUTDIS is 4 bits at bit #20. (not 24-21)
2. ftpmu010.c: enhance features and fix relocation
- The following functions is added for pmu features.
ftpmu010_mfpsr_select_dev()
ftpmu010_sdramhtc_set()
- This patch also fix the declare statement for relocation.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

Because twl4030 now has its own device files, move and rename
twl4030_mmc_config.
twl4030_mmc_config initializes the twl4030 power setting to
the mmc device. Because it is in the twl4030 power domain, move
it out of drivers/mmc/omap3_mmc.c and into drivers/power/twl4030.c.
The function was renamed to twl4030_power_mmc_init because all
the functions in this file are to have the format
twl4030_power_<device>_<action>
In this case the suffix is mmc_init so
device : mmc
action : init

Because twl4030 now has its own device files, move exiting
omap3 power_init_r to a new location.
power_init_r is the only function in board/omap3/common.
It initializes the twl4030 power for the board and enables
the led.
The power part of the the function is moved to twl4030_power_init in
drivers/power/twl4030.c The power compilation is conditional on the
existing config variable CONFIG_TWL4030_POWER.
The led part is moved to twl4030_led_init in the new file
drivers/misc/twl4030_led.c The led compilation is conditional on
the new config variable CONFIG_TWL4030_LED
The directory board/omap3/common was removed because power_init_r
was the only function in it.

The Zoom2 power reset button is on the top right side of the
main board. Press and hold for about to 8 seconds to completely
reset the board.
Some of the beta boards have a hardware problem that prevents
using this feature. If is difficult to further characterize the
boards that fail. So disable resetting for all beta boards.
The Zoom1 reset button is the red circle on the top right,
front of the board. Press and hold the button for 8 seconds to
completely reset the board.
After analyzing beagle, it was determined that other boards
that use the twl4030 for power managment can also make use
this function.
The resetting is done by the power management part of the twl4030.
Since there is no existing drivers/power, add one.
The compilation of power/twl4030.h is controlled by the config
variable CONFIG_TWL4030_POWER
