types.h must be included in imx-regs.h if one wants to include
imx-regs.h in a board configuration file. That for one's part is
necessary, if one wants to use addresses defined in imx-regs.h.

For example, fsl_esdhc.c needs CONFIG_SYS_FSL_ESDHC_ADDR defined and
a proper thing is to define it with IMX_MMC_SDHCx_BASE in board
configuration file. This patch fixes the build in that case.

8c38b5d03d MX53: add function to set SATA clock to internal
The MX53 SATA interface can use an internal clock (USB PHY1)
instead of an external clock. This is an undocumented feature, but used
on most Freescale's evaluation boards, such as MX53-loco.

As stated by Freescale's support:

Fuses (but not pins) may be used to configure SATA clocks.
Particularly the i.MX53 Fuse_Map contains the next information
about configuring SATA clocks :
	SATA_ALT_REF_CLK[1:0] (offset 0x180C)

'00' - 100MHz (External)
'01' - 50MHz (External)
'10' - 120MHz, internal (USB PHY)

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)

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.

031ed2fa74 i2c: Add support for designware i2c controller
Earlier, a driver exists in the u-boot source for designware i2c interface. That
driver was specific to spear platforms. This patch implements the i2c controller
as a generic driver which can be used by multiple platforms

The driver files are now renamed to designware_i2c.c and designware_i2c.h and
these are moved into drivers/i2c folder for reusability by other
platforms

96666a39ae DMA: Split the APBH DMA init into block and channel init
This fixes the issue where mxs_dma_init() was called either twice or never,
without introducing any new init hooks.

The idea is to allow each and every device using the APBH DMA block to
configure and request only the channels it uses, instead of making it call init
for all the channels as is now.

The common DMA block init part, which only configures the block, is then called
from CPUs arch_cpu_init() call.

4b3a30e9ae mx6q: define GPIO macros for translating between ordinals and port:index
The interface to the mxc_gpio driver uses integer (ordinal) values to
refer to all GPIOs on the i.MX processors. The registers themselves
and much of the i.MX documentation are banked in groups of 32, and these
macros allow the use of the port:index numbering for clarity.

GPIO_NUMBER() converts to ordinal value from port:index
GPIO_PORT() returns the port of an ordinal value
GPIO_INDEX() returns the index or offset of the ordinal.

Before we can send a command we need both the DATI (command inhibit on
mmc_dat line) bit and CMDI (command inhibit on mmc_cmd line) are clear.
The previous behavior of only checking on DATI was insufficient on some
cards and incorrect behavior in any case.  This makes the code check
for both bits being clear and makes the error print more clear as
to what happened.  DATI_CMDDIS is removed as it was unused elsewhere
in the code and stood for 'DATI is set, cmds are disabled still'.
