spl: Kconfig: migrate $(SPL_TPL_)LDSCRIPT to Kconfig

2017-08-13T15:12:34+00:00

Now that we have split up SPL_LDSCRIPT into a SPL and TPL variant and
have started to use the TPL-variant for the RK3368, it's time to clean
up behind ourselves: move both variants into Kconfig and remove them
from the whitelist.

spl: allow a separate TEXT_BASE, LDSCRIPT and MAX_SIZE for TPL

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

For the bringup of the RK3368, we need to support TPL and SPL running
from different addresses... which requires both stages to use a
distinct TEXT_BASE.

This commit adds support for having a separate LDSCRIPT for TPL (which
is expected to make use of the TPL_MAX_SIZE define) and for having a
the option of defining TPL_TEXT_BASE and having the TPL stage linked
against this address.

Note that the handling of the TEXT_BASE is designed to not interfere
with the previous assumption that SPL_TEXT_BASE should be used for TPL
as well, unless TPL_TEXT_BASE is defined.  For this reason, the test
in Makefile.spl uses the following (seemingly redundant checks):
 1. looks for $(SPL_TPL_)TEXT_BASE
 2. looks for SPL_TEXT_BASE (even when building in TPL)

spl: dm: Kconfig: split OF_CONTROL and OF_PLATDATA between SPL and TPL

2017-08-13T15:12:20+00:00

For the RK3368, we want to use OF_PLATDATA in TPL, but full OF_CONTROL
in SPL: this requires the introduction of a new family of
configuration options to decouple SPL_OF_CONTROL and SPL_OF_PLATDATA
from TPL.

Consequently, Makefile.spl needs to be adjusted to test for these
configuration items through the $(SPL_TPL_) macro instead of
hard-coding the SPL variant.

fdt: Makefile: Build python libfdt library if needed

2017-06-02T16:17:50+00:00

This is needed by binman and dtoc, so if those are being used, check that
the library is present and complain if not. Make sure that any error
appears on stderr so that buildman notices it.

This means that the fallback library (which uses fdtget) will not be used
anymore and swig will need to be installed to use binman / dtoc.

This affects any board which uses binman (currently sunxi and x86) or dtoc
(anything that uses CONFIG_SPL_OF_PLATDATA, currently some rockchip
boards).

sunxi: Store the device tree name in the SPL header

2017-05-17T17:53:58+00:00

This patch updates the mksunxiboot tool to optionally add
the default device tree name string to the SPL header. This
information can be used by the firmware upgrade tools to
protect users from harming themselves by trying to upgrade
to an incompatible bootloader.

The primary use case here is a non-removable bootable media
(such as NAND, eMMC or SPI flash), which already may have
a properly working, but a little bit outdated bootloader
installed. For example, the user may download or build a
new U-Boot image for "Cubieboard", and then attemept to
install it on a "Cubieboard2" hardware by mistake as a
replacement for the already existing bootloader. If this
happens, the flash programming tool can identify this
problem and warn the user.

The size of the SPL header is also increased from 64 bytes
to 96 bytes to provide enough space for the device tree name
string.

spl: Makefile: include /config in the (reduced) FDT used by the SPL stage

2017-05-12T02:03:40+00:00

When OF control is enabled for the SPL stage, nodes are removed from
the DTB to reduce its size. While /chosen is kept, /config is removed.

There's no reason why /chosen should be kept over /config (and as we
would like to put properties into /config that control the SPL stage),
we add '/config' to the list of nodes to be retained for the SPL stage.

Makefile: Fix linking with modern binutils

2017-04-10T12:06:48+00:00

Since Binutils 1a9ccd70f9a7[1] u-boot will not link targets that set
CONFIG_SYS_TEXT_BASE=0 with the following error:

  LD      u-boot
arm-linux-gnueabi-ld.bfd: u-boot: Not enough room for program headers, try
 linking with -N
arm-linux-gnueabi-ld.bfd: final link failed: Bad value

The issue can be reproduced with the bad binutils and the rock2_defconfig
target.

This issue was also encountered by the powerpc kernel[2], with the fix
being to pass --no-dynamic-linker for linkers newer than 2.26 when this
flag was introduced. The option tells ld that the PIE or shared lib does
not need loaded program headers.

Ubuntu Zesty's Binutils 2.27.51.20161202 hits this error.

scripts: sunxi: Build an raw SPL image

2017-04-07T05:53:46+00:00

Introduce a new sunxi-spl-with-ecc.bin image with already the right header,
ECC, randomizer and padding for the BROM to be able to read it.

It needs to be flashed using a raw access to the NAND so that the
controller doesn't change a thing to it, since we already have all the
right parameters.

Makefile: Provide an option to select SPL or TPL

2017-04-05T20:36:58+00:00

At present we have SPL_ which can be used in Makefiles to select between
normal and SPL CONFIGs like this:

    obj-$(CONFIG_$(SPL_)DM)		+= core/

When TPL is being built, SPL_ has the value 'SPL' which is generally a
good idea since they tend to follow each other. But in extreme situations
we may want to distinugish between SPL and TPL. For example we may not
want to enable CONFIG_DM with TPL.

Add a new SPL_TPL_ variable which is set to either empty (for U-Boot
proper), 'SPL' or 'TPL'. This may prove useful with TPL-specific options.

dm: allow limiting pre-reloc markings to spl or tpl

2017-03-16T22:03:44+00:00

Right now the u-boot,dm-pre-reloc flag will make each marked node
always appear in both spl and tpl. But systems needing an additional
tpl might have special constraints for each, like the spl needing to
be very tiny.

So introduce two additional flags to mark nodes for only spl or tpl
environments and introduce a function dm_fdt_pre_reloc to automate
the necessary checks in code instances checking for pre-relocation
flags.

The behaviour of the original flag stays untouched and still marks
a node for both spl and tpl.
