U-Boot for initial L2 SRAM uses L2 memory-mapping mode and not L2 with
locked lines. P2020 reference manual about L2 memory-mapping mode says:
Accesses to memory-mapped SRAM are cacheable only in the corresponding
e500 L1 caches.
So there is no need to set Caching-Inhibit I-bit for second part of initial
L2 SRAM mapping in TLB entry. Remove it. First part of initial L2 SRAM
mapping already does not have I-bit set.

QorIQ U-Boot binary for SD card booting compiled during build process
(either u-boot.bin or u-boot-with-spl.bin) cannot be directly loaded by
QorIQ pre-PBL BootROM. Compiled U-Boot binary first needs to be processed
by Freescale boot_format tool as described in doc/README.mpc85xx-sd-spi-boot
BootROM requires that image on SD card must contain special boot sector.
Implement support for generating this special boot sector directly in
U-Boot start code. Boot sector needs to be at the beginning of the image,
so when compiling only proper U-Boot without SPL then it needs to be in
proper U-Boot. When compiling SPL with proper U-Boot then it needs to be
only in SPL.
Support can be enabled by a new config option FSL_PREPBL_ESDHC_BOOT_SECTOR.
Via other two additional options FSL_PREPBL_ESDHC_BOOT_SECTOR_START and
FSL_PREPBL_ESDHC_BOOT_SECTOR_DATA it is possible to tune how final U-Boot
image could be stored on the SD card.

The generic ARM relocate_code function was using its own function entry
point as a relocation base, and it was obtaining that address by using
the "adr" instruction on that entry point label.
However that label is not just an ordinary label, instead we explicitly
mark it as a function start address. Normally that doesn't change much
(other than for debugging), but when assembled in Thumb mode, newer
versions of the GNU assembler prepare everything for this address being
used as the argument to a "bx" call, so make sure bit 0 is set in there
to mark this function as Thumb code. Of course this doesn't end up very
well when we use this address for the ensuing memcpy operation.
To avoid this problem, and to solve it in a robust way, add an extra
label, which is not marked as a function entry, and use that for the adr
instruction. This lets all assemblers generate the right immediate offset
in the "adr" instruction.
This fixes in particular ARMv7-M ports when using GNU binutils v2.37 or
newer (commit d3e52e120b68 seems to trigger the change in behaviour).
