Makefile: Don't mess with .text section location for selected arches
Most of architectures have .text section situated in the very beginning
of U-Boot binary and thus it is very logical that CONFIG_SYS_TEXT_BASE
is used on final linkage step to specify where U-Boot gets linked to.
For that we pass the following construction to the LD:
---------------------------->8-----------------------
xxx-ld ... -Ttext $(CONFIG_SYS_TEXT_BASE) ...
---------------------------->8-----------------------
But there could be exceptions. For example:
1. In case of ARCv2 we want to put vectors table in its own section
.ivt in front of .text section which means we need either add an
offset to CONFIG_SYS_TEXT_BASE to compensate for .ivt or don't
pass "-Ttext" to the LD at all and specify link base in linker
script directly.
2. Some architectures even though have .text section in the very
beginning of the U-Boot image still use different symbols to
specify link-base:
* NIOS2: CONFIG_SYS_MONITOR_BASE (which I really like because
that exactly what makes sense - where out image starts but not
beginning of its .text section which just happened to match the
whole image beginning)
* EXTENSA: CONFIG_SYS_TEXT_ADDR
* X86: Which doesn't use CONFIG_SYS_MONITOR_BASE in case of EFI
otherwise sets explicit link base in u-boot.lds
I think that's good to allow for flexibility and don't require each and
every architecture or even platform to specify CONFIG_SYS_TEXT_BASE as well
as use it to set .text section location.
So let's only pass "-Ttext xxx" for those architectures who don't set
link-base explicitly in their linker scripts.

After settings the speed of the sd with the switch command, a check is
done to make sure that the new speed has been set. The current check has a
masking error: speed are encoded on 4 bits only.
Fix it by masking the upper bits.
This fixes a problem seen with QEmu emulating a vexpress-a15.

ARM: DRA7x/AM57x: Add MMC/SD fixups for rev1.0 and rev 1.1
Since DRA7xx/AM57xx SR1.1 and SR1.0 has errata to limit the frequency of
MMC1 to 96MHz and frequency of MMC2 to 48MHz for AM572x SR1.1, limit the
frequency and disable higher speed modes for those revision.
Also use the recommended IO delays (those tagged with "rev11")

dts: am57xx-beagle-x15: disable UHS and HS200 support
The UHS modes are not supported in beagle-x15 because it's not possible to
switch the IO lines supply voltage to 1.8v.
Also HS200 cannot be supported on mmc2, because the IO lines of mmc2 are
connected to 3.3v.
ARM: dts: DRA7: use new dra7-specific compatible string
Use the new compatible string "ti,dra7-hsmmc" that was specifically
added for dra7 and dra72. This is required since for dra7 and dra72
processors iodelay values has to be set unlike other processors.

Now that omap_hsmmc has support for hs200 mode, change the clock
frequency to 192MHz. Also change the REFERENCE CLOCK frequency to
192MHz based on which the internal mmc clock divider is calculated.

mmc: omap_hsmmc: add signal voltage selection support
I/O data lines of UHS SD card operates at 1.8V when in UHS speed
mode (same is true for eMMC in DDR and HS200 modes). Add support
to switch signal voltage to 1.8V in order to support
UHS cards and eMMC HS200 and DDR modes.

mmc: omap_hsmmc: Add support to get pinctrl values and max frequency for different hw revisions
AM572x SR1.1 requires different IODelay values to be used than that used
in AM572x SR2.0. These values are populated in device tree. Add
capability in omap_hsmmc driver to extract IOdelay values for different
silicon revision. The maximum frequency is also reduced when using a ES1.1.
To keep the ability to boot both revsions with the same dtb, those values
can be provided by the platform code.

mmc: omap_hsmmc: Add support to set IODELAY values
The data manual of J6/J6 Eco recommends to set different IODELAY values
depending on the mode in which the MMC/SD is enumerated in order to
ensure IO timings are met.
Add support to parse mux values and iodelay values from device tree
and set these depending on the enumerated MMC mode.
