| * omap5: Expand CONFIG_SPL_MAX_SIZE and comment upon SRAM_SCRATCH_SPACE_ADDRTom Rini2013-08-28-1/+10
| | | | | | | | | | | | | | | | | | After examining both TRMs and doing some experimentation, we can rely on using the start of the download area for CONFIG_SPL_TEXT_BASE and then move SRAM_SCRATCH_SPACE_ADDR up, just like am335x. This is required for peripheral boot modes such as UART. Signed-off-by: Tom Rini <trini@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ARM: OMAP5: Fix warm reset with USB cable connectedLokesh Vutla2013-05-10-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Warm reset on OMAP5 freezes when USB cable is connected. Fix requires PRM_RSTTIME.RSTTIME1 to be programmed with the time for which reset should be held low for the voltages and the oscillator to reach stable state. There are 3 parameters to be considered for calculating the time, which are mostly board and PMIC dependent. -1- Time taken by the Oscillator to shut + restart -2- PMIC OTP times -3- Voltage rail ramp times, which inturn depends on the PMIC slew rate and value of the voltage ramp needed. In order to keep the code in u-boot simple, have a way for boards to specify a pre computed time directly using the 'CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC' option. If boards fail to specify the time, use a default as specified by 'CONFIG_DEFAULT_OMAP_RESET_TIME_MAX_USEC' instead. Using the default value translates into some ~22ms and should work in all cases. However in order to avoid this large delay hiding other bugs, its recommended that all boards look at their respective data sheets and specify a pre computed and optimal value using 'CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC' In order to help future board additions to compute this config option value, add a README at doc/README.omap-reset-time which explains how to compute the value. Also update the toplevel README with the additional option and pointers to doc/README.omap-reset-time.

* OMAP3/4/5/AM33xx: Correct logic for checking FAT or RAW MMCTom Rini2013-04-08-0/+2
| | | | | | | | | | | | | | | 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).

* OMAP4+: Force DDR in self-refresh after warm resetLokesh Vutla2012-07-07-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Errata ID:i727 Description: The refresh rate is programmed in the EMIF_SDRAM_REF_CTRL[15:0] REG_REFRESH_RATE parameter taking into account frequency of the device. When a warm reset is applied on the system, the OMAP processor restarts with another OPP and so frequency is not the same. Due to this frequency change, the refresh rate will be too low and could result in an unexpected behavior on the memory side. Workaround: The workaround is to force self-refresh when coming back from the warm reset with the following sequence: • Set EMIF_PWR_MGMT_CTRL[10:8] REG_LP_MODE to 0x2 • Set EMIF_PWR_MGMT_CTRL[7:4] REG_SR_TIM to 0x0 • Do a dummy read (loads automatically new value of sr_tim) This will reduce the risk of memory content corruption, but memory content can't be guaranteed after a warm reset.
