SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

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.

spl: rename config item SPL_ATF_SUPPORT to SPL_ATF

2017-11-25T23:39:07+00:00

Having CONFIG_SPL_ATF seems more natural.
Rename it, while it it is easy and there's few boards that use it
(only RK3399 and RK3368 boards).

spl: add serial download protocol (SDP) support

2017-08-23T08:41:58+00:00

Add USB serial download protocol support to SPL. If the SoC started
in recovery mode the SPL will immediately switch to SDP and wait for
further downloads/commands from the host side.

spl: fix Makefile for NOR, XIP and YMODEM

2017-08-17T08:15:24+00:00

During the the conversion to $(SPL_TPL_), the SPL_ fragment was
left over for the NOR, XIP and YMODEM boot methods in SPL, making
these unselectable.

This commit fixes this by dropping the spurious 'SPL_' fragment
from each line.

spl: consistently use $(SPL_TPL_) to select features for SPL and TPL builds

2017-08-13T15:12:21+00:00

To allow for a finer-grained control of features for TPL and SPL
builds all modules/boot-methods/etc. need to be consistently selected
based on the $(SPL_TPL_) macros.

This allows splitting the associated config-options in Kconfig: we
don't split the Kconfig options here and now, as this should happen on
an as-needed basis, whenever someone needs a feature/boot-method/etc.
in their TPL.

spl: add a 'return to bootrom' boot method

2017-08-13T15:12:19+00:00

Some devices (e.g. the RK3368) have only limited SRAM, but provide
support for loading the next boot stage after our SPL performs basic
setup (e.g. DRAM).

For target systems like these, we add a boot device BOOTROM that will
invoke a board-specific hook to return to the bootrom (if supported).

Enable support for XIP (execute in place) of U-Boot or kernel image. There is
no need to copy image from flash to ram if flash supports execute in place.

spl: add support to booting with ATF

2017-05-15T14:38:09+00:00

ATF(ARM Trusted Firmware) is used by ARM arch64 SoCs, find more infomation
about ATF at: https://github.com/ARM-software/arm-trusted-firmware

SPL is considered as BL2 in ATF terminology, it needs to load other parts
of ATF binary like BL31, BL32, SCP-BL30, and BL33(U-Boot). And needs to
prepare the parameter for BL31 which including entry and image information
for all other images. Then the SPL handle PC to BL31 with the parameter,
the BL31 will do the rest of work and at last get into U-Boot(BL33).

This patch needs work with patches from Andre for SPL support multi
binary in FIT.

The entry point of bl31 and bl33 are still using hard code because we
still can not get them from the FIT image information.

spl: spi: Move the generic SPI loader into common/spl

2016-10-06T19:07:33+00:00

All the other SPL loaders are in this directory, so move the SPI one in
there too.

There are two board-specific SPI loaders (fsl and sunxi). These remain in
the drivers/mtd/spi directory, since they do not contain generic code.
