libfdt: move headers to and

2018-03-05T15:16:28Z

Thomas reported U-Boot failed to build host tools if libfdt-devel package is installed because tools include libfdt headers from /usr/include/ instead of using internal ones. This commit moves the header code: include/libfdt.h -> include/linux/libfdt.h include/libfdt_env.h -> include/linux/libfdt_env.h and replaces include directives: #include -> #include #include -> #include Reported-by: Thomas Petazzoni Signed-off-by: Masahiro Yamada

arm64: show_regs: Dump the LRs HW values

2018-02-23T15:40:51Z

These were dropped in [1], after relocation, for their values offset by reloc_off. Unconditionally show the HW values and add a '(reloc)' hint for the offset values showed after relocation. Also, the LRs' dumps are now formatted the same way the other regs' are. [1] Commit 082693f4 ("arm64 :show_regs: show the address before relocation") Signed-off-by: Karl Beldan

arm/PSCI: support PSCI versions greater than 1.0

2018-02-14T17:14:15Z

ATF recently began announcing PSCI v1.1. Since that version is unknown to u-boot, the PSCI device nodes were not updated. Switch from the case statement to a greater/less-than comparison so that v1.1, as well as future versions, get at least the compatible nodes of known versions. PSCI v1.1 doesn't seem to have introduced a new corresponding compatible. Signed-off-by: Andre Heider

ARM: image: indent with tab instead of 4 spaces

2018-02-14T04:24:22Z

Commit 6808ef9ac2a6 ("move booti_setup to arch/arm/lig/image.c") not only moved the code, but also replaced a tab with 4 spaces to break the Linux coding style. Restore tab indentation. Signed-off-by: Masahiro Yamada Reviewed-by: Bin Chen

efi_loader: fix building crt0 on arm

2018-02-09T23:24:00Z

Before the patch an undefined constant EFI_SUBSYSTEM was used in the crt0 code. The current version of binutils does not swallow the error. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=888403 The necessary constant IMAGE_SUBSYSTEM_EFI_APPLICATION is already defined in pe.h. So let's factor out asm-generic/pe.h for the image subsystem constants and use it in our assembler code. IMAGE_SUBSYSTEM_SAL_RUNTIME_DRIVER does not exist in the specification let's use IMAGE_SUBSYSTEM_EFI_ROM instead. The include pe.h is only used in code maintained by Alex so let him be the maintainer here too.

move booti_setup to arch/arm/lig/image.c

2018-02-08T03:06:11Z

Follow bootz's pattern by moving the booti_setup to arch/arm/lib. This allows to use booti_setup in other paths, e.g booting an Android image containing Image format. Note that kernel relocation is move out of booti_setup and it is the caller's responsibility to do it and allows them do it differently. say, cmd/booti.c just do a manually, while in the bootm path, we can use bootm_load_os(with some changes).

efi_selftest: test start image

2018-01-22T22:09:14Z

This pair of tests checks the StartImage boot service. Each test loads an EFI application into memory and starts it. One returns by calling the Exit boot service. The other returns directly. The tests are not built on x86_64 because the relocation code for the efi binary cannot be created. Signed-off-by: Heinrich Schuchardt Signed-off-by: Alexander Graf

ARM: bootm: don't assume sp is in DRAM bank 0

2018-01-12T17:12:31Z

arch_lmb_reserve() currently assumes that the stack pointer is within DRAM bank 0. This is not necessarily true. Enhance the code to search through DRAM banks until the bank that does contain SP is found, and then reserve the tail of that bank.

ARMv8: Allow dynamic early stack pointer

2018-01-12T16:52:11Z

U-Boot typically uses a hard-coded value for the stack pointer before relocation. Implement option SYS_INIT_SP_BSS_OFFSET to instead calculate the initial SP at run-time. This is useful to avoid hard-coding addresses into U-Boot, so that can be loaded and executed at arbitrary addresses and thus avoid using arbitrary addresses at runtime. This option's value is the offset added to &_bss_start in order to calculate the stack pointer. This offset should be large enough so that the early malloc region, global data (gd), and early stack usage do not overlap any appended DTB. Signed-off-by: Stephen Warren Signed-off-by: Tom Warren
