arm: Add Kconfig symbols used for Linux asm compatibility

2017-06-05T18:13:13+00:00

Rather than change asm files that come from Linux, add the symbols
to Kconfig. Since one of the symbols is for thumb2 builds, make
CPU_V7M always select them.

armv8: fsl: move ccn504 code into FSL Makefile

2017-05-17T17:50:50+00:00

The generic ARMv8 assembly code contains routines for setting up
a CCN interconnect, though the Freescale SoCs are the only user.
Link this code only for Freescale targets, this saves some precious
bytes in the chronically tight SPL.

armv8: SPL: only compile GIC code if needed

2017-05-17T17:50:31+00:00

Not every SoC needs to set up the GIC interrupt controller, so link
think code only when the respective config option is set.
This shaves off some bytes from the SPL code size.

spl: fdt: support for fdt fixup for falcon boot

2017-05-12T02:04:26+00:00

Adding support for fdt fixup to update the
memory node in device tree for falcon boot.

This is needed for single stage or falcon
bootmode, to pass memory configuration to
kernel through DT memory node.

arm: Migrate SYS_THUMB_BUILD to Kconfig, introduce SPL_SYS_THUMB_BUILD

2017-03-19T00:28:01+00:00

Today, we have cases where we wish to build all of U-Boot in Thumb2 mode for
various reasons.  We also have cases where we only build SPL in Thumb2 mode due
to size constraints and wish to build the rest of the system in ARM mode.  So
in this migration we introduce a new symbol as well, SPL_SYS_THUMB_BUILD to
control if we build everything or just SPL (or in theory, just U-Boot) in
Thumb2 mode.

ARM: Default to using optimized memset and memcpy routines

2017-01-20T20:38:01+00:00

We have long had available optimized versions of the memset and memcpy
functions that are borrowed from the Linux kernel.  We should use these
in normal conditions as the speed wins in many workflows outweigh the
relatively minor size increase.  However, we have a number of places
where we're simply too close to size limits in SPL and must be able to
make the size vs performance trade-off in those cases.

armv8: prevent using THUMB

2017-01-04T15:37:40+00:00

The predominantely 32-bit ARM targets try to compile the SPL in Thumb
mode to reduce code size.
The 64-bit AArch64 instruction set does not know an alternative, concise
encoding, so the Thumb build option should only be set for 32-bit
targets.
Likewise -marm machine options are only valid for ARMv7 targets.

efi_loader: Allow to compile helloworld.efi w/o bundling it

2016-11-27T14:53:39+00:00

Today we can compile a self-contained hello world efi test binary that
allows us to quickly verify whether the EFI loader framwork works.

We can use that binary outside of the self-contained test case though,
by providing it to a to-be-tested system via tftp.

This patch separates compilation of the helloworld.efi file from
including it in the u-boot binary for "bootefi hello". It also modifies
the efi_loader test case to enable travis to pick up the compiled file.
Because we're now no longer bloating the resulting u-boot binary, we
can enable compilation always, giving us good travis test coverage.
