2013-07-02ARM: OMAP: GPIO: Fix valid range and enable usage of all GPIOs on OMAP5Axel Lin
The omap_gpio driver is used by AM33XX, OMAP3/4, OMAP54XX and DRA7XX SoCs. These SoCs have different gpio count but currently omap_gpio driver uses hard coded 192 which is wrong. This patch fixes this issue by: 1. Move define of OMAP_MAX_GPIO to all arch/arm/include/asm/arch-omap*/gpio.h. 2. Update gpio bank settings and enable GPIO modules 7 & 8 clocks for OMAP5. Thanks for Lubomir Popov to provide valuable comments to fix this issue.

2013-07-02am33xx: fix the ddr_cmdtctrl structureIlya Ledvich
Fix the wrong mapping between the DDR I/O control registers on AM33XX SoCs and the software representation in the SPL code. The most recent public TRM defines the following DDR I/O control registers offsets: * ddr_cmd0_ioctrl : offset 0x44E11404 * ddr_cmd1_ioctrl : offset 0x44E11408 * ddr_cmd2_ioctrl : offset 0x44E1140C * ddr_data0_ioctrl: offset 0x44E11440 * ddr_data1_ioctrl: offset 0x44E11444 While the struct ddr_cmdtctrl has also some reserved bits in the beginning. The struct is mapped to the address 0x44E11404. As a result "cm0ioctl" points to the ddr_cmd1_ioctrl register, "cm1ioctl" to the ddr_cmd2_ioctrl and etc. Registers ddr_cmd0_ioctrl and ddr_data0_ioctrl are never configured because of this mapping mismatch.

2013-06-06am33xx/omap4+: Move SRAM_SCRATCH_SPACE_ADDR to <asm/arch/omap.h>Tom Rini
The location of valid scratch space is dependent on SoC, so move that there. On OMAP4+ we continue to use SRAM_SCRATCH_SPACE_ADDR.

We need to call the save_omap_boot_params function on am33xx/ti81xx and other newer TI SoCs, so move the function to boot-common. Only OMAP4+ has the omap_hw_init_context function so add ifdefs to not call it on am33xx/ti81xx. Call save_omap_boot_params from s_init on am33xx/ti81xx boards.

2013-06-04am33xx: Correct NON_SECURE_SRAM_START/ENDTom Rini
Prior to Sricharan's cleanup of the boot parameter saving code, we did not make use of NON_SECURE_SRAM_START on am33xx, so it wasn't a problem that the address was pointing to the middle of our running SPL. Correct to point to the base location of the download image area. Increase CONFIG_SPL_TEXT_BASE to account for this scratch area being used. As part of correcting these tests, make use of the fact that we've always been placing our stack outside of the download image area (which is fine, once the downloaded image is run, ROM is gone) so correct the max size test to be the ROM defined top of the download area to where we link/load at.

2013-04-08OMAP3/4/5/AM33xx: Correct logic for checking FAT or RAW MMCTom Rini
In the case of booting from certain peripherals, such as UART, we must not see what the device descriptor says for RAW or FAT mode because in addition to being nonsensical, it leads to a hang. This is why we have a test currently for the boot mode being within range. The problem however is that on some platforms we get MMC2_2 as the boot mode and not the defined value for MMC2, and in others we get the value for MMC2_2. This is required to fix eMMC booting on omap5_uevm. Tested on am335x_evm (UART, NAND, SD), omap3_beagle (NAND, SD on classic, SD only on xM rev C5) and omap5_uevm (SD, eMMC).

Having said that, during validation it has been observed that, RTC clock need couple of seconds delay to stabilize the RTC OSC clock; and such a huge delay is not acceptable in kernel especially during early init and also it will impact quick/fast boot use-cases.
