arch: Add explicit linker script for u-boot-elf

2020-04-03T15:52:55+00:00

Commit f4dc714aaa2d ("arm64: Turn u-boot.bin back into an ELF file after
relocate-rela")
introduce REMAKE_ELF option to recreate u-boot.elf from u-boot ->
u-boot.bin + DT -> u-boot.elf.

The best is to ilustrate it from make V=1 output
  cat u-boot-nodtb.bin dts/dt.dtb > u-boot-dtb.bin
  cp u-boot-dtb.bin u-boot.bin
aarch64-linux-gnu-objcopy -I binary -B aarch64 -O elf64-littleaarch64  u-boot.bin u-boot-elf.o
  aarch64-linux-gnu-ld.bfd u-boot-elf.o -o u-boot.elf --defsym="_start"=0x8000000 -Ttext=0x8000000

Last command has no explicit linker script passed that's why toolchain
internal linker script is used.
In Binutils 2.32 case it contains SIZEOF_HEADERS symbol which has changed
behavior by commit
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=64029e93683a266c38d19789e780f3748bd6a188
which result in situation that program headers has changed from
(xilinx_zynqmp_mini_defconfig)

Program Headers:
  Type           Offset             VirtAddr           PhysAddr
                 FileSiz            MemSiz              Flags  Align

Xilinx tools like XSDB or Bootgen are using program headers for loading ELF
to the right location and by above binutils change ELF is loaded to
incorrect location.

The patch is explicitly use u-boot-elf.lds (just cat now) for u-boot.elf
recreation which is called when REMAKE_ELF is setup.
By purpose u-boot-elf.lds doesn't contain OUTPUT_FORMAT/OUTPUT_ARCH to be
able to use by all archs.

sunxi: Move common defconfig options to Kconfig

2020-03-18T12:55:00+00:00

Some config symbols are found in *almost* every _defconfig file for
Allwinner boards, because those options are actually a platform choice,
and not a per-board decision.
Some of these options are older, some have recently been added.

Move those options to be set for all Allwinner boards in their
respective Kconfig files.

The rationales are as follows:
- NR_DRAM_BANKS: All Allwinner SoC map DRAM at one contiguous region of
  address space only, starting at 1 GB. So it's always one bank.
- SPL_{DOS,EFI}_PARTITION: The Allwinner SPL does only support raw MMC
  accesses, we don't care about filesystems or partitions in there, so
  there is no need to define those symbols at all.
- USE_PREBOOT: We start USB early when a keyboard is configured, using the
  preboot env variable, so we need to set this variable.
- SYS_RELOC_GD_ENV_ADDR: We don't specify any ENV_ADDR, so need this
  symbol to be set (according to 8d8ee47e03e).
- SYS_USB_EVENT_POLL_VIA_INT_QUEUE: According to commit eab9433aa55428,
  specifying this reduces the latency of the USB keyboard handling, so
  this was formerly enabled in config headers for all Allwinner boards.

Kconfigs: layerscape: use a convenient default value for SYS_MALLOC_F_LEN

2020-02-04T10:50:25+00:00

The default value of CONFIG_SYS_MALLOC_F_LEN (0x400)
leaves U-Boot with not enough memory to load i2c driver
before relocate, causing it to hang.

Change the default value of CONFIG_SYS_MALLOC_F_LEN
for below SoCs,
- LS1012A
- LS1021A
- LS1043A

mkimage: fit: add support to encrypt image with aes

This commit add the support of encrypting image with aes
in mkimage. To enable the ciphering, a node cipher with
a reference to a key and IV (Initialization Vector) must
be added to the its file. Then mkimage add the encrypted
image to the FIT and add the key and IV to the u-boot

arm64: zynqmp: Add support for u-boot.itb generation with ATF

2020-01-14T08:05:54+00:00

Follow i.MX, Sunxi, RISC-V and Rockchip to generate u-boot.itb which
includes U-Boot proper, ATF and DTBs in FIT format. ZynqMP supports FIT for
quite a long time but with using out of tree solution. The patch is filling
this gap.

Tested on zcu102, zcu104 and zcu100/Ultra96.

spl: fit: allocate a temporary buffer to load the overlays

2020-01-07T16:12:47+00:00

If the node describing an overlay does not specify a load address, it will
be loaded at the address previously used.
Fixing it by allocating a temporary buffer that will be used as a
default load address. By default, the size of the buffer is 64kB which
should be plenty for most use cases.

spl: fit: Add support for applying DT overlay

2020-01-07T16:12:47+00:00

doc/uImage.FIT/overlay-fdt-boot.txt is describing how to create FIT
image with DT overlays in it.
Add support for this feature to SPL.

Here is the ZynqMP fragment where dtb points to full DT and dtbo is
overlay which should be applied on the top of dtb.
config {
        description = "ATF with full u-boot overlay";
        firmware = "atf";
        loadables = "uboot";
        fdt = "dtb", "dtbo";
};

The whole feature depends on OF_LIBFDT_OVERLAY which is adding +4kB code
and 0 for platforms which are not enabling this feature.

x86: Add an option to control the position of U-Boot

2019-12-15T03:44:19+00:00

The existing work-around for positioning U-Boot in the ROM when it
actually runs from RAM still exists and there is not obvious way to change
this.

Add a proper Kconfig option to handle this case. This also adds a new bool
property to indicate whether CONFIG_SYS_TEXT_BASE exists.

Kconfig: Enable building of u-boot.itb on Rockchip platform

2019-11-23T14:29:49+00:00

For all the Rockchip SoCs with SPL_LOAD_FIT enable, we need to build
u-boot.itb with U-Boot proper and ATF/OPTEE.

All the Rockchip boards with SPL_LOAD_FIT now supports FIT generator to
get ATF/OPTEE binary path from environment and pass the build even if no
ATF/OPTEE binary exist, so we can enable this feature for the rockchip
platform.
