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.

x86: Add SPL build rules for start-up code

spl: Don't create a BSS padding when it is separate

2017-02-06T03:38:46+00:00

When BSS does not immediate follow the SPL image we don't need padding
before the device tree. Remove it in this case.

This Makefile variable can be used in the architecture's main Makefile but
at present it is not set up until later. Set it just before this Makefile is

Makefile: preserve output for images that can contain HAB Blocks

2017-01-02T16:07:39+00:00

To being able to sign created binaries, we need to know the HAB Blocks
for that image. Especially for the imximage type the HAB Blocks are
only available during creation of the image. We want to preserve the
information until we get to sign the files.
In the verbose case we still get them printed out instead of writing
to log files.

v2-Changes:
 - No usage of MKIMAGEOUTPUT_$(@F) macro.
 - Predefine default value /dev/null in every involved Makefile.

spl: dfu: move DFU Kconfig to SPL Kconfig

2016-11-29T00:49:49+00:00

The DFU Kconfig menu entries should be part of the SPL
Kconfig file. Also avoid using the top level Makefile by
moving the config dependent build artifacts to the driver/
and driver/usb/gadget/ Makfiles.

With that, DFU can be built again in SPL if
CONFIG_SPL_DFU_SUPPORT is enabled.
