armv8: New MMU setup code allowing to use 48+ bits PA/VA

2016-01-19T22:25:36+00:00

This patch adds code which sets up 2-level page tables on ARM64 thus
extending available VA space. CPUs implementing 64k translation
granule are able to use direct PA-VA mapping of the whole 48 bit
address space.
It also adds the ability to reset the SCTRL register at the very beginning
of execution to avoid interference from stale mappings set up by early
firmware/loaders/etc.

armv8: LS2080A: Rename LS2085A to reflect LS2080A

2015-11-30T16:53:04+00:00

LS2080A is a prime personality of Freescale’s LS2085A. It is a non-AIOP
personality without support of DP-DDR, L2 switch, 1588, PCIe endpoint etc.
So renaming existing LS2085A code base to reflect LS2080A (Prime personality)

omap-common: Common boot code OMAP3 support and cleanup

2015-07-27T19:02:03+00:00

This introduces OMAP3 support for the common omap boot code, as well as a
major cleanup of the common omap boot code.

First, the omap_boot_parameters structure becomes platform-specific, since its
definition differs a bit across omap platforms. The offsets are removed as well
since it is U-Boot's coding style to use structures for mapping such kind of
data (in the sense that it is similar to registers). It is correct to assume
that romcode structure encoding is the same as U-Boot, given the description
of these structures in the TRMs.

The original address provided by the bootrom is passed to the U-Boot binary
instead of a duplicate of the structure stored in global data. This allows to
have only the relevant (boot device and mode) information stored in global data.
It is also expected that the address where the bootrom stores that information
is not overridden by the U-Boot SPL or U-Boot.

The save_omap_boot_params is expected to handle all special cases where the data
provided by the bootrom cannot be used as-is, so that spl_boot_device and
spl_boot_mode only return the data from global data.

All of this is only relevant when the U-Boot SPL is used. In cases it is not,
save_boot_params should fallback to its weak (or board-specific) definition.
save_omap_boot_params should not be called in that context either.

armv8/fsl-lsch3: Add support for second DDR clock

2015-02-24T21:09:14+00:00

FSL-LSCH3 platforms can have multiple DDR clocks. LS2085A has one clock for
general DDR controlers, and another clock for DP-DDR. DDR driver needs to
change to support multiple clocks.

ARM: make gd a function for clang

2014-09-09T11:51:08+00:00

"clang does not support global register variables; this is
unlikely to be implemented soon because it requires additional
LLVM backend support" [1]

Workaround it by obtaining the value of gd/r9 by an inline
asm routine. Note there is no set routine added for ARM at the
moment, since most if not all updates of gd from c are actually
not needed for ARM.

ARM: use r9 for gd

2013-09-23T16:00:02+00:00

To be more EABI compliant and as a preparation for building
with clang, use the platform-specific r9 register for gd
instead of r8.

note: The FIQ is not updated since it is not used in u-boot,
and under discussion for the time being.

The following checkpatch warning is ignored:
