Matrix keyboards require a key map to be set up, and must also deal with
key ghosting.
Create a keyboard matrix management implementation which can be leveraged
by various keyboard drivers. This includes code to read the keymap from
the FDT and perform debouncing.

This patch imports parts of two patches from the Freescale U-Boot with the following
commit messages:
ENGR00156405 ESDHC: Add workaround for auto-clock gate errata ENGcm03648
http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/commit/drivers/mmc/imx_esdhc.c?h=imx_v2009.08_12.01.01&id=e436525a70fe47623d346bc7d9f08f12ff8ad787
The errata, not applicable to USDHC, causes ESDHC to shut off clock to the card
when auto-clock gating is enabled for commands with busy signalling and no data
phase. The card might require the clock to exit the busy state, so the workaround
is to disable the auto-clock gate bits in SYSCTL register for such commands. The
workaround also entails polling on DAT0 bit in the PRSSTAT register to learn when
busy state is complete. Auto-clock gating is re-enabled at the end of busy state.
ENGR00156670-1 ESDHC/USDHC: Remove delay before each cmd and some bug fixes
http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/commit/drivers/mmc/imx_esdhc.c?h=imx_v2009.08_12.01.01&id=a77c6fec8596891be96b2cdbc742c9824844b92a
Removed delay of 10 ms before each command. There should not be a need to have this
delay after the ENGR00156405 patch that polls until card is not busy anymore before
proceeding to next cmd.
This patch imports the polling part of both patches. The auto-clock gating code
don't apply for i.MX6 as implemented in these two patches.
SYSCTL_RSTA was defined twice. Remove one definition.

According to OMAP3 TRM, when the controller reports certain errors,
driver must perform a software reset. This is done by setting a bit
in SYSCTL and waiting it to clear:
- SRC on command timeout (CTO)
- SRD on data errors (DTO, DCRC and DEB)
This fixes a problem seen on OMAP3 pandora board with some cards
that won't work with a message printed multiple times:
timedout waiting on cmd inhibit to clear

For the powerpc processors with SRIO interface, boot location can be configured
from SRIO1 or SRIO2 by RCW. The processor booting from SRIO can do without flash
for u-boot image. The image can be fetched from another processor's memory
space by SRIO link connected between them.
The processor boots from SRIO is slave, the processor boots from normal flash
memory space and can help slave to boot from its memory space is master.
They are different environments and requirements:
master:
1. NOR flash for its own u-boot image, ucode and ENV space.
2. Slave's u-boot image in master NOR flash.
3. Normally boot from local NOR flash.
4. Configure SRIO switch system if needed.
slave:
1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV.
2. Boot location should be set to SRIO1 or SRIO2 by RCW.
3. RCW should configure the SerDes, SRIO interfaces correctly.
4. Slave must be powered on after master's boot.
5. Must define CONFIG_SYS_QE_FMAN_FW_IN_REMOTE because of no ucode
locally.
For the slave module, need to finish these processes:
1. Set the boot location to SRIO1 or SRIO2 by RCW.
2. Set a specific TLB entry for the boot process.
3. Set a LAW entry with the TargetID SRIO1 or SRIO2 for the boot.
4. Slave's u-boot image should be generated specifically by
make xxxx_SRIOBOOT_SLAVE_config.
This will set SYS_TEXT_BASE=0xFFF80000 and other configurations.
