2017-07-12imx: reorganize IMX code as other SOCsStefano Babic
Change is consistent with other SOCs and it is in preparation for adding SOMs. SOC's related files are moved from cpu/ to mach-imx/<SOC>. This change is also coherent with the structure in kernel.

2017-01-20serial, ns16550: bugfix: ns16550 fifo not enabledHeiko Schocher
commit: 65f83802b7a5b "serial: 16550: Add getfcr accessor" breaks u-boot commandline working with long commands sending to the board. Since the above patch, you have to setup the fcr register. For board/archs which enable OF_PLATDATA, the new field fcr in struct ns16550_platdata is not filled with a default value ... This leads in not setting up the uarts fifo, which ends in problems, when you send long commands to u-boots commandline. Detected this issue with automated tbot tests on am335x based shc board. The error does not popup, if you type commands. You need to copy&paste a long command to u-boots commandshell (or send a long command with tbot) Possible boards/plattforms with problems: ./arch/arm/cpu/arm926ejs/lpc32xx/devices.c ./arch/arm/mach-tegra/board.c ./board/overo/overo.c ./board/quipos/cairo/cairo.c ./board/logicpd/omap3som/omap3logic.c ./board/logicpd/zoom1/zoom1.c ./board/timll/devkit8000/devkit8000.c ./board/lg/sniper/sniper.c ./board/ti/beagle/beagle.c ./drivers/serial/serial_rockchip.c Signed-off-by: Heiko Schocher <hs@denx.de> Signed-off-by: Ladislav Michl <ladis@linux-mips.org> Tested-by: Adam Ford <aford173@gmail.com> Reviewed-by: Tom Rini <trini@konsulko.com>

2016-08-26ARM: Move SYS_CACHELINE_SIZE over to KconfigTom Rini
This series moves the CONFIG_SYS_CACHELINE_SIZE. First, in nearly all cases we are mirroring the values used by the Linux Kernel here. Also, so long as (and in this case, it is true) we implement flushes in hunks that are no larger than the smallest implementation (and given that we mirror the Linux Kernel, again we are fine) it is OK to align higher. The biggest changes here are that we always use 64 bytes for CPU_V7 even if for example the underlying core is only 32 bytes (this mirrors Linux). Second, we say ARM64 uses 64 bytes not 128 (as found in the Linux Kernel) as we do not need multi-platform support (to this degree) and only the Cavium ThunderX 88xx series has a use for such large alignment.

2015-12-01ARM: mxs: fix VDDD brownout settingMichael Heimpold
At the moment, the desired brownout is at 1.0V. However, this setting cannot be realized by hardware since we have only 3 bits to represent the voltage difference from the target value. Target value is 1500 mV, brownout target is 1000 mV, voltage steps are 25 mV. Register content calculation: (1500 [mV] - 1000 [mV]) / 25 [mV] = 20 (decimal) = 0x14 Register takes only 3 bits, that is 0x4. But 0x4 * 25 [mV] = 100 [mV], that means that actual brownout level is 1500 [mV] - 100 [mV] = 1.4 V. Minimum possible BO level is 1500 [mV] - 0x7 * 25 [mV] = 1315 [mV]. So lets use this value as desired BO value (which is also the same as FSL bootlets use).

2015-09-02arm: mxs: Fix mkimage invocationMarek Vasut
Remove this ad-hoc mkimage invocation in MXS Makefile and replace it with the standard mkimage rule instead. This patch fixes recent build issues introduced by the patch 92a655c mkimage: Set up a file size parameter and keep it updated These build issues could be triggered by building for example the MX28EVK and the u-boot.sb image: $ make mx28evk_defconfig $ make V=1 u-boot.sb [...] make -f ./scripts/Makefile.build obj=arch/arm/cpu/arm926ejs/mxs u-boot.sb ./tools/mkimage -n arch/arm/cpu/arm926ejs/mxs/mxsimage.mx28.cfg -T mxsimage u-boot.sb ./tools/mkimage: Can't open (null): Bad address arch/arm/cpu/arm926ejs/mxs/Makefile:82: recipe for target 'u-boot.sb' failed make[1]: *** [u-boot.sb] Error 1 Makefile:989: recipe for target 'u-boot.sb' failed make: *** [u-boot.sb] Error 2 With this patch: ./tools/mkimage -n arch/arm/cpu/arm926ejs/mxs/mxsimage.mx28.cfg -T mxsimage -d arch/arm/cpu/arm926ejs/mxs/mxsimage.mx28.cfg u-boot.sb Signed-off-by: Marek Vasut <marex@denx.de> Cc: Simon Glass <sjg@chromium.org> Cc: Juha Lumme <juha.lumme@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>

Since lowlevel_init() is only referenced from start.S, it should not be declared inline at all.

2015-08-12ARM: cache: implement a default weak flush_cache() functionWu, Josh
Current many cpu use the same flush_cache() function, which just call the flush_dcache_range(). So implement a weak flush_cache() for all the cpus to use. In original weak flush_cache() in arch/arm/lib/cache.c, there has some code for ARM1136 & ARM926ejs. But in the arch/arm/cpu/arm1136/cpu.c and arch/arm/cpu/arm926ejs/cache.c, there implements a real flush_cache() function as well. That means the original code for ARM1136 & ARM926ejs in weak flush_cache() of arch/arm/lib/cache.c is totally useless. So in this patch remove such code in flush_cache() and only call flush_dcache_range(). Signed-off-by: Josh Wu <josh.wu@atmel.com>
2015-08-12ARM: cache: add an empty stub function for invalidate/flush dcacheWu, Josh
Since some driver like ohci, lcd used dcache functions. But some ARM cpu don't implement the invalidate_dcache_range()/flush_dcache_range() functions. To avoid compiling errors this patch adds an weak empty stub function for all ARM cpu in arch/arm/lib/cache.c. And ARM cpu still can implemnt its own cache functions on the cpu folder.

2015-08-12nand: lpc32xx: add SLC NAND controller supportVladimir Zapolskiy
The change adds support of LPC32xx SLC NAND controller. LPC32xx SoC has two different mutually exclusive NAND controllers to communicate with single and multiple layer chips. This simple driver allows to specify NAND chip timings and defines custom read_buf()/write_buf() operations, because access to 8-bit data register must be 32-bit aligned. Support of hardware ECC calculation is not implemented (data correction is always done by software), since it requires a working DMA engine. The driver can be included to an SPL image.

2015-08-11net: lpc32xx: add RMII phy mode supportVladimir Zapolskiy
LPC32xx MAC and clock control configuration requires some minor quirks to deal with a phy connected by RMII. It's worth to mention that the kernel and legacy BSP from NXP sets SUPP_RESET_RMII == (1 << 11) bit, however the description of this bit is missing in shared LPC32x0 User Manual UM10326 Rev. 3, July 22, 2011 and in LPC32x0 Draft User Mannual Rev. 00.27, November 20, 2008, also in my tests an SMSC LAN8700 phy device connected over RMII seems to work correctly without touching this bit. Add support of RMII, if CONFIG_RMII is defined, this option is aligned with a number of boards, which already define the same config value.

2015-04-22ARM: mxs: Get boot mode from OCRAMJörg Krause
Reading the boot mode pins after power-up does not necessarily represent the boot mode used by the ROM loader. For example the state of a pin may have changed because a recovery switch which was pressed to enter USB mode is already released after plugging in USB. The ROM loader stores the value a fixed address in OCRAM. Use this value instead of reading the boot map pins. The GLOBAL_BOOT_MODE_ADDR for i.MX28 is taken from an U-Boot patch for the MX28EVK: http://repository.timesys.com/buildsources/u/u-boot/u-boot-2009.08/u-boot-2009.08-mx28-201012211513.patch Leave the boot mode detection for the i.MX23 untouched. Someone has to test whether the i.MX ROM loader does also store the boot mode in OCRAM and if the address match.
