2017-04-27pinctrl: Kconfig: sort pinctrl config options to prevent future clutterPhilipp Tomsich
This originally started out as "pinctrl: Kconfig: reorder to keep Rockchip options together" and tried to keep the Rockchip-related config options together. However, we now rewrite all chip-specific driver selections to start with CONFIG_PINCTRL_ (with the inadvertent changes to related Makefiles) and sort those alphabetically. And as this already means touching most of the file, we also reformat the help text to not exceed 80 characters (but make full use of those 80 characters).

Video driver for older Allwinner SoCs uses cfb console framework which in turn uses struct ctfb_res_modes to hold timing informations. However, DM video framework uses different structure - struct display_timing. It makes more sense to convert lcdc to use new timing structure because all new drivers should use DM video framework and older drivers might be rewritten to use new framework too.

2017-04-18sysreset: psci: support system reset in a generic way with PSCIMasahiro Yamada
If the system is running PSCI firmware, the System Reset function (func ID: 0x80000009) is supposed to be handled by PSCI, that is, the SoC/board specific reset implementation should be moved to PSCI. U-Boot should call the PSCI service according to the arm-smccc manner. The arm-smccc is supported on ARMv7 or later. Especially, ARMv8 generation SoCs are likely to run ARM Trusted Firmware BL31. In this case, U-Boot is a non-secure world boot loader, so it should not be able to reset the system directly. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

So header will also be copied from SD to DDR. - CONFIG_MAX_SPL_SIZE is limited to 90KB. SPL is copied to OCRAM (128K) where 32K are reserved for use by boot ROM and 6K for the header. - Reduce the size of CAAM driver for SPL Blobification functions and descriptors, that are not required at the time of SPL are disabled.

The warm-reset of rk3188 socs keeps the remap setting as it was, so if it was enabled, the cpu would start from address 0x0 of the sram instead of address 0x0 of the bootrom, thus making the reset hang.

We should invalidate the dcache before starting the DMA. In case there are any dirty lines from the DMA buffer in the cache, subsequent cache-line replacements may corrupt the buffer in memory while the DMA is still going on. Cache-line replacement can happen if the CPU tries to bring some other memory locations into the cache while the DMA is going on.

2017-04-14usb: dwc3: gadget: make cache-maintenance on event buffers more robustPhilipp Tomsich
Merely using dma_alloc_coherent does not ensure that there is no stale data left in the caches for the allocated DMA buffer (i.e. that the affected cacheline may still be dirty). The original code was doing the following (on AArch64, which translates a 'flush' into a 'clean + invalidate'): # during initialisation: 1. allocate buffers via memalign => buffers may still be modified (cached, dirty) # during interrupt processing 2. clean + invalidate buffers => may commit stale data from a modified cacheline 3. read from buffers This could lead to garbage info being written to buffers before reading them during even-processing. To make the event processing more robust, we use the following sequence for the cache-maintenance: # during initialisation: 1. allocate buffers via memalign 2. clean + invalidate buffers (we only need the 'invalidate' part, but dwc3_flush_cache() always performs a 'clean + invalidate') # during interrupt processing 3. read the buffers (we know these lines are not cached, due to the previous invalidation and no other code touching them in-between) 4. clean + invalidate buffers => writes back any modification we may have made during event processing and ensures that the lines are not in the cache the next time we enter interrupt processing Note that with the original sequence, we observe reproducible (depending on the cache state: i.e. running dhcp/usb start before will upset caches to get us around this) issues in the event processing (a fatal synchronous abort in dwc3_gadget_uboot_handle_interrupt on the first time interrupt handling is invoked) when running USB mass storage emulation on our RK3399-Q7 with data-caches on.

2017-04-14usb: dwc3: ensure consistent types for dwc3_flush_cachePhilipp Tomsich
The dwc3_flush_cache() call was declared and used inconsistently: * The declaration assumed 'int' for addresses (a potential issue when running in a LP64 memory model). * The invocation cast the address to 'long'. This change ensures that both the declaration and usage of this function consistently uses 'uintptr_t' for correct behaviour even when the allocated buffers (to be flushed) reside outside of the lower 32bits of memory.
