* ppc: rename arch/ppc/ to arch/powerpc/Masahiro Yamada2020-05-0447-2772/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In old days, Linux supported PowerPC with two arch directories, arch/ppc/ and arch/ppc64/. Linux commit 564ee7a5668e ("[PATCH] powerpc: Move arch/ppc*/kernel/vecemu.c to arch/powerpc") started the migration to arch/powerpc/, and commit 917f0af9e5a9 ("powerpc: Remove arch/ppc and include/asm-ppc") finished it. This commit aligns the directory name with the current Linux. I did 'git mv arch/ppc/ arch/powerpc/', and fixed up some hard-coded arch/ppc paths. Barebox has stuck to arch/ppc/ for a long time. To keep the backward compatibility, I added the following to the top Makefile. # Support ARCH=ppc for backward compatibility ifeq ($(ARCH),ppc) SRCARCH := powerpc endif Both ARCH=ppc and ARCH=powerpc work in the same way.

* lds: Add and use RO_DATA_SECTION macroSascha Hauer2019-10-141-8/+1
| | | | | | | | | We have many different pointer arrays which we put into linker sections and each time there's one added we have to adjust all linker scripts. This adds a common RO_DATA_SECTION define and uses it for all architectures. This makes it easier to add a new linker array. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* lds: Move start/end address variables into definesSascha Hauer2019-10-141-19/+2
| | | | | | | | | | | For the older section defines we specify the start and end addresses outside the macro which means we have to repeat them in each linker script. Make the start/end addresses part of the define to simplify things. While at it, add a BAREBOX_ prefix to the INITCALLS and EXITCALLS macros for consistency to the other defines.

* ratp: implement generic command supportAleksander Morgado2018-03-011-0/+4
| | | | | | | | | | | | | | | | | | | The RATP implementation now allows executing generic commands with a binary interface: binary requests are received and binary responses are returned. Each command can define its own RATP request contents (e.g. to specify command-specific options) as well as its own RATP response contents (if any data is to be returned). Each command is associated with a pair of numeric unique request and response IDs, and for easy reference these IDs are maintained in the common ratp_bb header. Modules may override generic implemented commands or include their own new ones (as long as the numeric IDs introduced are unique).

| * defaultenv: add defaultenv-1 in boards via defaultenv_append_directory()Sascha Hauer2016-10-1017-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently it's hardcoded for each board which defaultenv version is used. This is unfortunate since some people like the other defaultenv version better and may want to select it. This patch removes the board specific environment path CONFIG_DEFAULT_ENVIRONMENT_PATH and instead adds it via: if (IS_ENABLED(CONFIG_DEFAULT_ENVIRONMENT_GENERIC)) defaultenv_append_directory(defaultenv_<board>); This way we can make sure that the defaultenv-1 board specific bits are only compiled in when defaultenv-1 is actually in use. The next step is to make the defaultenv version selection a user visible choice. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* PPC: fix size optimisationJuergen Borleis2016-05-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since patch e92abad36307d the linker discards sections which seems not used to make the image smaller. But this change will discard the whole init and exception code from start.S which renders the final image useless.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to enable and use USB/OHCI on the MPC5200 the USB PLL register must be set. It's not easy to find a correct value for this register, it seems it depends on the used external reference frequency and some other 'magic' things. There are some values out in the wild for the 33,333333 MHz and 33,333000 MHz reference frequency case, but they are not consistent over the boards. The value used here in this change for the USB PLL register is from the first days of support for this platform and works at least on the reference baseboard.
