This updates the ddr_spd.h header file from U-Boot-2019.01 with some
small changes:

- typedefs are removed
- "_s" suffix from struct types removed
- remove unnecessary "extern" from function declarations

remap_range is for remapping regions with different cache attributes.
It is implemented for ARM and PowerPC only, the other architectures only
provide stubs.
Currently the new cache attributes are passed in an architecture specific
way and the attributes have to be retrieved by calls to
mmu_get_pte_cached_flags() and mmu_get_pte_uncached_flags().
Make this simpler by providing architecture independent flags which can
be directly passed to remap_range()
Also provide a MAP_ARCH_DEFAULT flag and a arch_can_remap() function.
The MAP_ARCH_DEFAULT defaults to whatever caching type the architecture
has as default. the arch_can_remap() function returns true if the
architecture can change the cache attributes, false otherwise. This
allows the memtest code to better find out what it has to do.

This introduces the bitsperlong.h file for the remaining architectures.
It's purpose is to define BITS_PER_LONG which in the next step can be used
by a generic posix_types.h file.

Instead of letting all architectures define their own dma_addr_t use
a common place in include/linux/types.h and use a Kconfig symbol that
architectures can select to define the width of dma_addr_t. The same
is done in the Kernel.

Add DDR3 support into the MPC8xxx DDR driver.

To avoid confusion, the function set_ddr_sdram_mode is renamed
set_ddr2_sdram_mode.

Checking for errors is simplified in the DDR2 DIMM parameters
computation to be consistent with DDR3.

This code is derived from the files found in directory drivers/ddr/fsl
from U-Boot version git-be937b5.

Removed the ppc bit operation functions and definitions in the ppc
file asm/bitops.h since these are already defined in the asm-generic header
files. Moved ffs64 definition to the mpc85xx header files because
the function requires the inclusion of linux/log2.h which also includes
asm/bitops.h.

The conflict was noted when UBIFS was enabled in barebox.

TLB support for the 85xx CPUs has been upgraded to support the MMUv2
page size definitions. This has been imported from U-Boot version
git-9407c3fc. This allows for future CPUs to make use of the new MMU
support.

Also the definition of MAX_MEM_MAPPED has been changed to avoid type
casting with "min" macro.
