* microblaze/PCI: Remove support for Xilinx PCI host bridgeThippeswamy Havalige2022-11-251-1/+0
| | | | | | | | | This patch removes support for the Xilinx PCI host bridge IPcore. Signed-off-by: Thippeswamy Havalige <thippeswamy.havalige@amd.com> Link: https://lore.kernel.org/r/20221025065214.4663-13-thippeswamy.havalige@amd.com Signed-off-by: Michal Simek <michal.simek@amd.com>
* treewide: defconfig: address renamed CONFIG_DEBUG_INFO=yArnd Bergmann2022-09-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CONFIG_DEBUG_INFO is now implicitly selected if one picks one of the explicit options that could be DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT, DEBUG_INFO_DWARF4, DEBUG_INFO_DWARF5. This was actually not what I had in mind when I suggested making it a 'choice' statement, but it's too late to change again now, and the Kconfig logic is more sensible in the new form. Change any defconfig file that had CONFIG_DEBUG_INFO enabled but did not pick DWARF4 or DWARF5 explicitly to now pick the toolchain default.

* microblaze: Remove noMMU codeMichal Simek2020-11-262-91/+0
| | | | | | | | | | | | | | | This configuration is obsolete and likely none is really using it. That's why remove it to simplify code. Note about CONFIG_MMU in hw_exception_handler.S is left intentionally for better comment understanding.

* microblaze: Wire CMA allocatorMichal Simek2020-02-041-0/+2
| | | | | | | | | | | Based on commit 04e3543e228f ("microblaze: use the generic dma coherent remap allocator") CMA can be easily enabled by calling dma_contiguous_reserve() at the end of mmu_init(). High limit is end of lowmem space which is completely unused at this point of time. Signed-off-by: Michal Simek <michal.simek@xilinx.com> Reviewed-by: Christoph Hellwig <hch@lst.de>

* microblaze: Switch to standard restart handlerLinus Walleij2019-09-192-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | The microblaze uses the legacy APIs to dig out a GPIO pin defined in the root of the device tree to issue a hard reset of the platform. Asserting a hard reset should be done using the standard DT-enabled and fully GPIO descriptor aware driver in drivers/power/reset/gpio-restart.c using the bindings from Documentation/devicetree/bindings/power/reset/gpio-restart.txt To achieve this, first make sure microblaze makes use of the standard kernel restart path utilizing do_kernel_restart() from <linux/reboot.h>. Put in some grace time and an emergency print if the restart does not properly assert. As this is basic platform functionality we patch the DTS file and defconfig in one go for a lockstep change.

* KEYS: CONFIG_KEYS_DEBUG_PROC_KEYS is no longer an optionDavid Howells2016-02-102-2/+0
| | | | | | | | | | | | | | | | | CONFIG_KEYS_DEBUG_PROC_KEYS is no longer an option as /proc/keys is now mandatory if the keyrings facility is enabled (it's used by libkeyutils in userspace). The defconfig references were removed with: perl -p -i -e 's/CONFIG_KEYS_DEBUG_PROC_KEYS=y\n//' \ `git grep -l CONFIG_KEYS_DEBUG_PROC_KEYS=y` and the integrity Kconfig fixed by hand.

* kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes2011-01-212-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.
