At present we support multiple environment drivers but there is not way to
select between them at run time. Also settings related to the position and
size of the environment area are global (i.e. apply to all locations).
Until these limitations are removed we cannot really support more than one
environment location. Adjust the location to be a choice so that only one
can be selected. By default the environment is 'nowhere', meaning that the
environment exists only in memory and cannot be saved.
Also expand the help for the 'nowhere' option and move it to the top since
it is the default.

Set up a location driver for each supported environment location. At
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.

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.
Data based on OMAP5432 Technical reference Manual SWPU282AF (May
2012-Revised Aug 2016)

Maximum Data Transfer Size (MDTS) field indicates the maximum
data transfer size between the host and the controller. The
host should not submit a command that exceeds this transfer
size. The value is in units of the minimum memory page size
and is reported as a power of two (2^n).
The spec also says: a value of 0h indicates no restrictions
on transfer size. On the real NVMe card this is normally not
0 due to hardware restrictions, but with QEMU emulated NVMe
device it reports as 0. In nvme_blk_read/write() below we
have the following algorithm for maximum number of logic
blocks per transfer:
u16 lbas = 1 << (dev->max_transfer_shift - ns->lba_shift);
dev->max_transfer_shift being 0 will for sure cause lbas to
overflow. Let's use 20. With this fix, the NVMe driver works
