tools: zynqimage: Add Xilinx Zynq boot header generation to mkimage

2015-11-19T12:09:21+00:00

As with other platforms vendors love to create their own boot header
formats. Xilinx is no different and for the Zynq platform/SoC there
exists the "boot.bin" which is read by the platforms bootrom. This
format is described to a useful extent within the Xilinx Zynq TRM.

This implementation adds support for the 'zynqimage' to mkimage. The
implementation only considers the most common boot header which is
un-encrypted and packed directly after the boot header itself (no
XIP, etc.). However this implementation does take into consideration the
other fields of the header for image dumping use cases (vector table and
register initialization).

image.c: Fix non-Android booting with ramdisk and/or device tree

2015-10-27T23:06:17+00:00

In 1fec3c5 I added a check that if we had an Android image we default to
trying the kernel address for a ramdisk.  However when we don't have an
Android image buf is NULL and we oops here.  Ensure that we have 'buf'
to check first.

common/image.c: Make boot_get_ramdisk() perform a check for Android images

2015-10-11T21:12:12+00:00

In 2dd4632 the check for where a ramdisk is found on an Android image
was got moved into the "normal" loop here, causing people to have to
pass the kernel address in the ramdisk address location in order to have
Android boot still.  This changed previous behavior so perform a check
early in the function to see if we have an Android image and if so use
that as where to look for the ramdisk (which is what the rest of the
code here expects).  We allow for this to still be overridden with an
explicit ramdisk address to be passed as normal.

Add support for LZ4 decompression algorithm

2015-10-11T21:12:10+00:00

This patch adds support for LZ4-compressed FIT image contents. This
algorithm has a slightly worse compression ration than LZO while being
nearly twice as fast to decompress. When loading images from a fast
storage medium this usually results in a boot time win.

Sandbox-tested only since I don't have a U-Boot development system set
up right now. The code was imported unchanged from coreboot where it's
proven to work, though. I'm mostly interested in getting this recognized
by mkImage for use in a downstream project.

rockchip: Add support for the SPI image

2015-09-03T03:28:23+00:00

The Rockchip boot ROM requires a particular file format for booting from SPI.
It consists of a 512-byte header encoded with RC4, some padding and then up
to 32KB of executable code in 2KB blocks, separated by 2KB empty blocks.

Add support to mkimage so that an SPL image (u-boot-spl-dtb.bin) can be
converted to this format. This allows booting from SPI flash on supported
machines.

rockchip: Add support for the SD image

2015-09-03T03:28:23+00:00

The Rockchip boot ROM requires a particular file format. It consists of
64KB of zeroes, a 512-byte header encoded with RC4, and then some executable
code.

Add support to mkimage so that an SPL image (u-boot-spl-dtb.bin) can be
converted to this format.

rockchip: Add the rkimage format to mkimage

2015-09-03T03:28:23+00:00

Rockchip SoCs require certain formats for code that they execute, The
simplest format is a 4-byte header at the start of a binary file. Add
support for this so that we can create images that the boot ROM understands.

image: Fix loop condition to avoid warning

2015-08-28T15:46:35+00:00

GCC 5.1 starts warning for comparisons such as !a > 0, assuming that the
negation was meant to apply to the whole expression rather than just the
left operand.

Indeed the comparison in the FIT loadable code is confusingly written,
though it does end up doing the right thing. Rewrite the condition to be
more explicit, that is, iterate over strings until they're exhausted.

image: fix Android ramdisk support when dtb is specified

2015-08-13T00:47:32+00:00

If a dtb is specified on the command-line, the Android boot image ramdisk
will not be found. Fix this so that we can specify the ramdisk address and
dtb address. The syntax is to enter the Android boot image address for
both the kernel and ramdisk.
