2016-05-10	7839011 Browse files » bootm: Move bootm options to common/Kconfig ... bootm has a C API, so the bootm options have to depend on the option providing the bootm code (CONFIG_BOOTM), not on the option providing the command (CONFIG_CMD_BOOTM). Fixing the dependencies makes it possible to fully use bootm from C without enabling the bootm command support. This also removes the CMD_ prefix from the options which means we have to update the defconfigs aswell. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 10 May 2016

2016-04-07	2096b4f Browse files » efi: let the generic relocate code handle all relocations ... Part of the barebox code and variables are put in separate sections (.barebox* and .initcall). When this code is compiled as position independent code then the compiler creates corresponding .rela.barebox and .rela.initcall* sections with the relocation table entries. These sections don't match the .rela.data* wildcard in the linker script. As a result, they are not added to the .rela section during linking but are added individually after it instead. And when the EFI binary is created from the ELF binary, these sections are not copied. This has two side effects: 1. The corresponding relocations are not handled by the generic relocation code. 'fixup_tables()' was added to do these relocations manually. 2. In the DYNAMIC section, the RELASZ entry contains the total size of relocations in bytes. This includes the .rela.barebox* and .rela.initcall* sections. This value is not modified when the EFI binary is created. So the value is too large. The generic relocation code in _relocate() used this value when iterating over all relocation entries. With the wrong RELASZ value it iterates beyond the end of the .rela section into uninitialized memory. After power-on this memory is zero and the relocation code interprets this as 'nothing to do', so there is no visible effect. After a soft reset, random data in that area may produce a seemingly valid relocation entry, a random address is modified and barebox crashes. This patch adds the .rela.barebox* and .rela.initcall* sections to the normal .rela section. The RELASZ now contains the correct size and the generic relocation code works correctly. 'fixup_tables()' must be removed at the same time to avoid relocating these entries twice.

2015-08-27	83b0a5a Browse files » restart: replace reset_cpu with registered restart handlers ... This replaces the reset_cpu() function which every SoC or board must provide with registered handlers. This makes it possible to have multiple reset functions for boards which have multiple ways to reset the machine. Also boards which have no way at all to reset the machine no longer have to provide a dummy reset_cpu() function. The problem this solves is that some machines have external PMICs or similar to reset the system which have to be preferred over the internal SoC reset, because the PMIC can reset not only the SoC but also the external devices. To pick the right way to reset a machine each handler has a priority. The default priority is 100 and all currently existing restart handlers are registered with this priority. of_get_restart_priority() allows to retrieve the priority from the device tree which makes it possible for boards to give certain restart handlers a higher priority in order to use this one instead of the default one.
