2015-01-22sunxi: Hookup OTG USB controller supportHans de Goede
Hookup OTG USB controller support and enable the otg controller + USB-keyb on various tablets. This allows tablet owners to interact with u-boot without needing to solder a serial console onto their tablet PCB.

2015-01-22sunxi: video: Use frontend for dma on sun4i to fix memory bandwidth problemsHans de Goede
Testing has shown that on sun4i the display backend engine does not have deep enough fifo-s causing flickering / tearing in full-hd mode due to fifo underruns. On sun4i use the display frontend engine to do the dma from memory, as the frontend does have deep enough fifo-s. As added advantage of this is that it results in much better memory bandwidth as it reduces the amount of dram bank switches, for more details see: http://ssvb.github.io/2014/11/11/revisiting-fullhd-x11-desktop-performance-of-the-allwinner-a10.html Note that this changes the pipeline searched for in the simplefb node, we can get away with doing this now, since no kernel has yet shipped with simplefb dtb nodes, and I will make sure to get a simplefb node with the new pipeline into 3.19 before it ships.

2015-01-22sunxi: Stop differentiating between 512M and 1G variants of the same boardHans de Goede
While working on adding more boards I noticed that we lack a config for the 512M cubieboard, and that some of the new boards which I want to add also have 512M and 1G variants, rather then adding 2 defconfig's for all of these, lets switch the exising boards which have both a 512M and 1024M variant over to the sun4i dram autoconfig code. This also drops the foo_RAMSIZE_defconfig variants of boards where we currently have 2 separate configs already. Note: 1) The newly introduced CONFIG_DRAM_EMR1 kconfig value is not used with a value other then its default for now, but we need this to be configurable to support some new boards with auto dram config. 2) We always set all CONFIG_DRAM_foo values in defconfigs, even if they match the defaults, this is done to make it more clear what values are used for a certain board. This has been tested on a Mele A1000, Mini-X and a Cubieboard, all 1G variants, the dram autoconfig code has also been tested on a 512M mk802 (a defconfig for the mk802 is added in a later patch).

2015-01-22sunxi: Move clock_get_pllX / clock_set_pllX protos to mach specific headersHans de Goede
Which pll-s are available depends on the machine type, move the clock_get_pllX / clock_set_pllX prototypes to the clock_sun?i.h header files so that we only declare what is actually available. e.g. clock_get_pll5p() is not available on sun6i / sun8i, and with sun9i we get a completely different set of plls.

2015-01-22sunxi: display: Make lcd display clk phase configurableHans de Goede
While running some tests with an Olinuxino-A13-Micro + a 7" Olimex LCD module I noticed that the screen flickered. This is caused by the lcd display clk phase reg value being set to 0, where it should be 1 in this setup. This commit adds a Kconfig option for the lcd display clk phase, so that we can set it per board. This defaults to 1, because looking at all the fex files in sunxi-boards, that is by far the most used value. This commit updated the Ippo and MSI Primo73 tablet defconfigs to override the default of 1 with 0, as that is the correct value for those tablets, this keeps the register settings the same as before this commit. The Olinuxino-A13 defconfigs are not updated, changing the register setting for these boards from 0 to 1, this is intentional.

2015-01-21sunxi: Restore lowlevel_init usageHans de Goede
2 recent sunxi changes have removed the usage of lowlevel_init by moving some code around and then setting CONFIG_SKIP_LOWLEVEL_INIT. This is problematic for 2 reasons: 1) It does not just stop s_init from being called, it also stops cpu_init_cp15 from getting called, which is undesirable. 2) We want u-boot.bin to be usable standalone, without SPL, some people e.g. use an upstream u-boot.bin together with Allwinner's boot0 loader. So u-boot.bin must (re)initialize the gpios, timer, etc. This commit restores the lowlevel_init / s_init usage, while keeping the changes to no longer use the global-data (gd) struct in the SPL.

2015-01-21MIPS: use common code from lib/time.cThomas Langer
The common code just needs the C0_COUNT as free running counter, without the need of writing and checking C0_COMPARE. The function get_tbclk() is still implemented here instead of changing all places of CONFIG_SYS_MIPS_TIMER_FREQ to CONFIG_SYS_TIMER_RATE. The change was tested on a MIPS32 system, but as the MIPS64 code was/is the same, this should be no problem. Signed-off-by: Thomas Langer <thomas.langer@lantiq.com>

2015-01-16sunxi: Move SPL s_init() code to board_init_f()Simon Glass
The current sunxi implementation uses gdata, which is going away. It also sets up DRAM before board_init_f() in SPL. There is really no reason to do much in s_init() since board_init_f() is called immediately afterwards. The only change is that we need our own implementation of board_init_f() which sets up DRAM before the BSS (which is in DRAM) is cleared. The s_init() code runs once for SPL and again for U-Boot proper. We shouldn't need to init the clock/timer/gpio/i2c init twice, so just have it in SPL. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-01-16arm: Add warnings about using gdataSimon Glass
We need to get rid of this SPL-specific setting of the global_data pointer. It is already set up in start.S immediately before board_init_f() is called, and there may be information there that is needed (e.g. pre-reloc malloc info). Signed-off-by: Simon Glass <sjg@chromium.org>
2015-01-16TI ARMv7: Don't use GD before crt0.S has set itTom Rini
Prior to this change we set the gd pointer early so that we can store data in it. This becomes problematic for DM changes as well as being odd in general. Re-work the code paths so that we don't need to set the gd pointer so early and instead can rely upon the normal setting of it. In order to do this we do need to move certain calls from s_init into spl_board_init(), mainly preloader_console_init and save_omap_boot_params.

2015-01-16arch/powerpc: Fix mapping of Freescale SerDes protocolsCodrin Ciubotariu
The number of supported serdes protocols on Freescale SoCs has increased over time. Until now, an u64 variable have been initialized on boot with the configured protocols. However, since this number has increased (enum srds_prtcl has more than 64 values), 64 bits are no longer sufficient to hold track of all the configured protocols. This patch replaces the u64 map values with static arrays. To keep track of the number of serdes protocols, the SERDES_PRCTL_COUNT vale has been added at the end of enum srds_prtcl. This value must always be the last one. Signed-off-by: Codrin Ciubotariu <codrin.ciubotariu@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>

2015-01-16powerpc: mpc85xx: Add dummy gpio.h to enable CONFIG_OF_CONTROLRuchika Gupta
If CONFIG_OF_CONTROL is enabled, lib/fdtdec.c is compiled. It includes <asm/gpio.h> and then <asm/gpio.h> includes <asm/arch/gpio.h>. As a result, all the SoCs that enable CONFIG_OF_CONTROL must have <asm/arch/gpio.h>. The right fix would be to split the lib/fdtdec.c to remove dependency on GPIO. This commit adds a dummy <asm/arch/gpio.h> to support OF_CONTROL for mpc85xx platform. A file mpc85xx_gpio.h exists in arch/powerpc/include/asm. The defintions in that file conflict with the ones in asm-generic/gpio.h. Hence a dummy header file has been added. This will be removed after FDT-GPIO stuff is fixed correctly.
