present this just points to the global functions and is not used. A
later patch will switch this over to use private functions in each driver.
There are several special cases here in various drivers to handle
peculiarities of certain boards:
1. Some boards define CONFIG_ENV_IS_IN_FAT and CONFIG_SPL_ENV_SUPPORT but
do not actually load the environment in SPL. The env load code was
optimised out before but with the driver, it is not. Therefore a special
case is added to env/fat.c. The correct fix (depending on board testing
might be to disable CONFIG_SPL_ENV_SUPPORT.
2. A similar situations happens with CONFIG_ENV_IS_IN_FLASH. Some boards
do not actually load the environment in SPL, so to reduce code size we
need to drop that code. A similar fix may be possible with these boards,
or it may be possible to adjust the environment CONFIG settings.
Added to the above is that the CONFIG_SPL_ENV_SUPPORT option does not
apply when the environment is in flash.
Obviously the above has been discovered through painful and time-consuming
trial and error. Hopefully board maintainers can take a look and figure
out what is actually needed.

ARM: OMAP5: Enable support for AVS0 for OMAP5 production devices
OMAP5432 did go into production with AVS class0 registers which were
mutually exclusive from AVS Class 1.5 registers.
Most OMAP5-uEVM boards use the pre-production Class1.5 which has
production efuse registers set to 0. However on production devices,
these are set to valid data.
scale_vcore logic is already smart enough to detect this and use the
"Nominal voltage" on devices that do not have efuse registers populated.
On a test production device populated as follows:
MPU OPP_NOM:
=> md.l 0x04A0021C4 1 4a0021c4: 03a003e9 ....
(0x3e9 = 1.01v) vs nom voltage of 1.06v
MPU OPP_HIGH:
=> md.l 0x04A0021C8 1 4a0021c8: 03400485 ..@.
MM OPP_NOM:
=> md.l 0x04A0021A4 1 4a0021a4: 038003d4 ....
(0x3d4 = 980mV) vs nom voltage of 1.025v
MM OPP_OD:
=> md.l 0x04A0021A8 1 4a0021a8: 03600403 ..`.
CORE OPP_NOM:
=> md.l 0x04A0021D8 1 4a0021d8: 000003cf ....
(0x3cf = 975mV) vs nom voltage of 1.040v
Since the efuse values are'nt currently used, we do not regress on
existing pre-production samples (they continue to use nominal voltage).
But on boards that do have production samples populated, we can leverage
the optimal voltages necessary for proper operation.
Tested on:
a) 720-2644-001 OMAP5UEVM with production sample.
b) 750-2628-222(A) UEVM5432G-02 with pre-production sample.
