2018-11-26arch: Move initrd= parsing into do_mounts_initrd.cFlorian Fainelli1-17/+0
ARC, ARM, ARM64 and Unicore32 are all capable of parsing the "initrd=" command line parameter to allow specifying the physical address and size of an initrd. Move that parsing into init/do_mounts_initrd.c such that we no longer duplicate that logic.

Now that we have central and global variables holding the physical address and size of the initrd, we can have early_init_dt_check_for_initrd() populate phys_initrd_start/phys_initrd_size for us. This allows us to remove a chunk of code from arch/arm/mm/init.c introduced with commit 65939301acdb ("arm: set initrd_start/initrd_end for fdt scan").

Make phys_initrd_start and phys_initrd_size global variables declared in init/do_mounts_initrd.c such that we can later have generic code in drivers/of/fdt.c populate those variables for us. This requires both the ARM and unicore32 implementations to be properly guarded against CONFIG_BLK_DEV_INITRD, and also initialize the variables to the expected default values (unicore32).

2018-11-27ARM: dts: uniphier: Add all CPUs in cooling mapsViresh Kumar1-2/+4
Each CPU can (and does) participate in cooling down the system but the DT only captures a handful of them, normally CPU0, in the cooling maps. Things work by chance currently as under normal circumstances its the first CPU of each cluster which is used by the operating systems to probe the cooling devices. But as soon as this CPU ordering changes and any other CPU is used to bring up the cooling device, we will start seeing failures. Also the DT is rather incomplete when we list only one CPU in the cooling maps, as the hardware doesn't have any such limitations. Update cooling maps to include all devices affected by individual trip points. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

The SAMA5D2 is different from SAMA5D3 and SAMA5D4, as there are two different clocks for the peripherals in the SoC. The Static Memory controller is connected to the divided master clock. Unfortunately, the device tree does not correctly show this and uses the master clock directly. This clock is then used by the code for the NAND controller to calculate the timings for the controller, and we end up with slow NAND Flash access. Fix the device tree, and the performance of Flash access is improved. Signed-off-by: Romain Izard <romain.izard.pro@gmail.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

2018-11-20crypto: chacha20-generic - refactor to allow varying number of roundsEric Biggers1-20/+20
In preparation for adding XChaCha12 support, rename/refactor chacha20-generic to support different numbers of rounds. The justification for needing XChaCha12 support is explained in more detail in the patch "crypto: chacha - add XChaCha12 support". The only difference between ChaCha{8,12,20} are the number of rounds itself; all other parts of the algorithm are the same. Therefore, remove the "20" from all definitions, structures, functions, files, etc. that will be shared by all ChaCha versions. Also make ->setkey() store the round count in the chacha_ctx (previously chacha20_ctx). The generic code then passes the round count through to chacha_block(). There will be a ->setkey() function for each explicitly allowed round count; the encrypt/decrypt functions will be the same. I decided not to do it the opposite way (same ->setkey() function for all round counts, with different encrypt/decrypt functions) because that would have required more boilerplate code in architecture-specific implementations of ChaCha and XChaCha.

Add pinctrl data for ddr_vtt_toggle pin so that it is configured for proper state during DeepSleep0. The pin should enter DS0 off mode and hold the line low so VTT regulator is kept off while suspended. It is also important for the PULLUP to be set on this pin so that on removal of isolation, the VTT line is pulled high as a requirement for bringing the DDR3 out of self-refresh. This toggling is dependent on the IO isolation controlled by the wkup_m3. Without placing the IOs into isolation the DS0 states set for the pin will not be latched into effect during suspend.

2018-11-19ARM: OMAP2+: prm44xx: Fix section annotation on omap44xx_prm_enable_io_wakeupNathan Chancellor1-1/+1
When building the kernel with Clang, the following section mismatch warning appears: WARNING: vmlinux.o(.text+0x38b3c): Section mismatch in reference from the function omap44xx_prm_late_init() to the function .init.text:omap44xx_prm_enable_io_wakeup() The function omap44xx_prm_late_init() references the function __init omap44xx_prm_enable_io_wakeup(). This is often because omap44xx_prm_late_init lacks a __init annotation or the annotation of omap44xx_prm_enable_io_wakeup is wrong. Remove the __init annotation from omap44xx_prm_enable_io_wakeup so there is no more mismatch.

2018-11-19ARM: OMAP2+: hwmod: Fix some section annotationsNathan Chancellor1-3/+3
When building the kernel with Clang, the following section mismatch warnings appears: WARNING: vmlinux.o(.text+0x2d398): Section mismatch in reference from the function _setup() to the function .init.text:_setup_iclk_autoidle() The function _setup() references the function __init _setup_iclk_autoidle(). This is often because _setup lacks a __init annotation or the annotation of _setup_iclk_autoidle is wrong. WARNING: vmlinux.o(.text+0x2d3a0): Section mismatch in reference from the function _setup() to the function .init.text:_setup_reset() The function _setup() references the function __init _setup_reset(). This is often because _setup lacks a __init annotation or the annotation of _setup_reset is wrong. WARNING: vmlinux.o(.text+0x2d408): Section mismatch in reference from the function _setup() to the function .init.text:_setup_postsetup() The function _setup() references the function __init _setup_postsetup(). This is often because _setup lacks a __init annotation or the annotation of _setup_postsetup is wrong. _setup is used in omap_hwmod_allocate_module, which isn't marked __init and looks like it shouldn't be, meaning to fix these warnings, those functions must be moved out of the init section, which this patch does.
