| * Exynos: Tidy up the pwm_config function in the exynos pwm driverGabe Black2013-04-01-16/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some small fixes in the exynos pwm driver: 1. NS_IN_HZ is non-sensical since these are not compatible units. This constant actually describes the number of nanoseconds in a second. Renamed it to NS_IN_SEC. Also dropped the unnecessary parenthesis. 2. The variable "period" is not used to hold a period, it's used to hold a frequency. Renamed it to "frequency". 3. tcmp is an unsigned value, so (tcmp < 0) will never be true and the if which checks that condition will never execute. Also, there should be no problem if the pwm never switches, so there's no reason to subtract one from tcmp and therefore no reason to compare it against zero. Removed both ifs. If they weren't removed, tcmp should be a signed value. 4. Add a check for a 0 period. Test with command "sf probe 1:0; time sf read 40008000 0 1000".

| * Exynos: Avoid a divide by zero by specifying a non-zero period for pwm 4Gabe Black2013-04-01-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pwm_config function in the exynos pwm driver divides by its period period parameter. A function was calling pwm_config with a 0ns period and a 0ns duty cycle. That doesn't actually make any sense physically, and results in a divide by zero in the driver. This change changes the parameters to be a 100000ns period and duty cycle. Test with command "sf probe 1:0; time sf read 40008000 0 1000".

| * Exynos: pwm: Fix two bugs in the exynos pwm configuration codeGabe Black2013-04-01-10/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First, the "div" value was being used incorrectly to compute the frequency of the PWM timer. The value passed in is a constant which reflects the value that would be found in a configuration register, 0 to 4. That should correspond to a scaling factor of 1, 2, 4, 8, or 16, 1 << div, but div + 1 was being used instead. Second, the reset value of the timers were being calculated to give an overall frequency, thrown out, and set to a maximum value. This was done so that PWM 4 could be used as the system clock by counting down from a high value, but it was applied indiscriminantly. It should at most be applied only to PWM 4. This change also takes the opportunity to tidy up the pwm_init function. Test with command "sf probe 1:0; time sf read 40008000 0 1000".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | timer_get_us returns the time in microseconds since a certain reference point of history. However, it does not guarantee to return an accurate time after a long period; instead, it wraps around (that is, the reference point is reset to some other point of history) after some periods.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When booting a Freescale kernel 3.0.35 on a Wandboard solo, the get_board_rev() returns 0x62xxx, which is not a value understood by the VPU (Video Processing Unit) library in the kernel and causes the video playback to fail. The expected values for get_board_rev are: 0x63xxx: For mx6quad/dual 0x61xxx: For mx6dual-lite/solo So adjust get_board_rev() accordingly and make it as weak function, so that we do not need to define it in every mx6 board file.

U-Boot 2013.01-10524-g432a3aa-dirty (Feb 07 2013 - 13:34:46) CPU: Freescale i.MX6Q rev1.1 at 792 MHz Reset cause: POR So due to revC POR/watchdog circuitry whenever a watchdog occurs, it causes a POR. Clearing the PDE - Power Down Enable bit of WMCR registers fixes the problem and is also safe for all mx6 boards.

| * | | | | ARM: implement some Cortex-A9 errata workaroundsStephen Warren2013-03-13-0/+19

Add code to implement the workarounds, enabled by new CONFIG_ options. This code was taken from the Linux kernel, v3.8, arch/arm/mm/proc-v7.S, and modified to remove the logic to conditionally apply the WAR (since we know exactly which CPU we're running on given the U-Boot configuration), and use r0 instead of r10 for consistency with the rest of U-Boot's cpu_init_cp15().

This causes relocation records of type R_ARM_ABS32 to become R_ARM_RELATIVE, which makes code which uses LGA able to run before relocation as well as after. Note: this affects more than ARM targets, as linker- lists span possibly all target architectures, notably PowerPC.

| * | | | Remove linker lists (LGAs) from SPL linker scriptsAlbert ARIBAUD2013-03-12-4/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many SPL linker scripts needlessly include linker lists (aka LGAs). Remove them whenever possible; keep it only in the seven am335x_evm variants (am335x_evm, am335x_evm_uart[1-5], am335x_evm_spiboot), where there is actual content in output section .u_boot_list.

Mapping output section .u_boot_list to memory .sram fixes these symbols' mapping. This modifies the SPL binary but has no functional impact, as __image_copy_end and _end are never used in SPLs and u_boot_list is empty for all 29 boards affected (omap4_sdp4430 eco5pk igep0030 am335x_evm_uart3 omap3_beagle am3517_crane igep0032 mt_ventoux pcm051 am3517_evm omap3_evm_quick_mmc am335x_evm_uart2 am335x_evm_spiboot am335x_evm_uart1 omap3_evm igep0030_nand omap3_overo igep0020 am335x_evm omap4_panda omap5_evm am335x_evm_uart4 devkit8000 tricorder mcx twister omap3_evm_quick_nand am335x_evm_uart5 igep0020_nand).
