When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

baord_init_f takes one argument, boot_flag. It has not been used for
powerpc, until recently changing to use generic board architecture.
The boot flag is added as a return value from cpu_init_f().

Freescale IFC controller has been used for mpc8xxx. It will be used
for ARM-based SoC as well. This patch moves the driver to driver/misc
and fix the header file includes.

Update CONFIG_RAMBOOT and CONFIG_NAND_SPL references to accept CONFIG_SPL
and CONFIG_SPL_BUILD, respectively. CONFIG_NAND_SPL can be removed once
the last mpc85xx nand_spl target is gone.
CONFIG_RAMBOOT will need to remain for other use cases, but it doesn't
seem right to overload it for meaning SPL as well as nand_spl does. Even
if it's somewhat appropriate for the main u-boot, the SPL itself isn't
(necessarily) ramboot, and we don't have separate configs for SPL and
main u-boot. It was also inconsistent, as other platforms such as
mpc83xx didn't use CONFIG_RAMBOOT in this way.

It applies to non-Freescale 85xx boards as well as Freescale boards,
so it doesn't belong in board/freescale. Plus, it needs to come out
of nand_spl if it's to be used by the new SPL.

During NAND_SPL boot, base address and different register are programmed
default by corresponding NAND controllers(eLBC/IFC). These settings are
sufficient enough for NAND SPL.
Avoid updating these register.They will be programmed during NAND RAMBOOT.

Issue: Address masking doesn't work properly.
When sum of the base address, defined by BA, and memory bank size,
defined by AM, exceeds 4GB (0xffff_ffff) then AMASKn[AM] doesn't mask
CSPRn[BA] bits.
Impact:
This will impact booting when we are reprogramming CSPR0(BA) and
AMASK0(AMASK) while executing from NOR Flash.
Workaround:
Re-programming of CSPR(BA) and AMASK is done while not executing from NOR
Flash. The code which programs the BA and AMASK is executed from L2-SRAM.

Add NAND support (including spl) on IFC, such as is found on the p1010.
Note that using hardware ECC on IFC with small-page NAND (which is what
comes on the p1010rdb reference board) means there will be insufficient
OOB space for JFFS2, since IFC does not support 1-bit ECC. UBI should
work, as it does not use OOB for anything but ECC.
When hardware ECC is not enabled in CSOR, software ECC is now used.

renaming 85xx define CONFIG_NAND_OR_PRELIM to CONFIG_SYS_NAND_OR_PRELIM
and CONFIG_NAND_BR_PRELIM to CONFIG_SYS_NAND_BR_PRELIM to use the more
appropriate CONFIG_SYS prefix as well as be consistent with 83xx.

Currently, 83xx, 86xx, and 85xx have a lot of duplicated code
dedicated to defining and manipulating the LBC registers. Merge
this into a single spot.
To do this, we have to decide on a common name for the data structure
that holds the lbc registers - it will now be known as fsl_lbc_t, and we
adopt a common name for the immap layouts that include the lbc - this was
previously known as either im_lbc or lbus; use the former.
In addition, create accessors for the BR/OR regs that use in/out_be32
and use those instead of the mismash of access methods currently in play.
I have done a successful ppc build all and tested a board or two from
each processor family.

As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.
Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.
