| | | | | | | | | | | | | | | | | | | | | | The omap4460_volts struct was incorrectly referencing tps62361 instead of twl6030 as PMIC for the core and mm voltages (the tps is used for mpu supply only). This shall lead to bad OPP settings while booting kernel. Fixing it. Fix some comments as well. Signed-off-by: Lubomir Popov <lpopov@mm-sol.com>

* | arm1176: Remove unused MMU setup from start.SBenoît Thébaudeau2013-04-12-90/+1
| | | | | | | | | | | | | | | | | | Following the removal of the smdk6400 board, the MMU setup code in arm1176/start.S becomes unused, so remove it. It will still be possible to restore it later from the Git history if necessary, in which case it should be moved out of the relocate_code() function.

* | imx: Add u-boot-with-nand-spl.imx make targetBenoît Thébaudeau2013-04-12-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | This image combines the SPL with the i.MX header, the FCB and U-Boot. For i.MX25/35/51, the FCB is ignored by the boot ROM, so this image is just useful because it can be programmed on a NAND Flash page boundary. For i.MX53, the FCB is required by the boot ROM. This does not support i.MX6 so far because its FCB is more complicated. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com>
* | imx: Add u-boot-with-spl.imx make targetBenoît Thébaudeau2013-04-12-0/+6
| | | | | | | | | | | | | | | | | | | | This image combines the SPL with the i.MX header and U-Boot. This is a convenient way of having a single image to program on some boot devices. The i.MX header has to be added to the SPL before appending U-Boot, so that the boot ROM loads only the SPL. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com>

* | imx: Fix automatic make targets for imx imagesBenoît Thébaudeau2013-04-12-2/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Automatically build the 'u-boot.imx' (i.e. imx header + u-boot.bin) and 'SPL' (i.e. imx header + u-boot-spl.bin) make targets for all imx processors supporting this header, so for arm926ejs, arm1136 and armv7. Some combinations were missing. At the same time, fix the build of SPL targets not supporting the imx header on arm1136. For arm1136, the 'SPL' make target was forced to build in all cases if CONFIG_SPL_BUILD was defined, even for non-imx platforms or imx setups without an imx header.

* | arm: crt0.S: Remove bogus .globlBenoît Thébaudeau2013-04-12-24/+4

* | arm: relocate_code(): Use __image_copy_end for end of relocationBenoît Thébaudeau2013-04-12-15/+64
| | | | | | | | | | | | | | | | | | | | | | | | Use __image_copy_end instead of __bss_start for the end of the image to relocate. This is the same as commit 033ca72, but applied to all ARM start.S. This is a more appropriate symbol naming for an image copy & relocate feature, and this also saves a useless copy of data put between __image_copy_end and __bss_start in linker scripts (e.g. relocation information, or MMU initialization tables used only before jumping to the relocated image).

* OMAP3/4/5/AM33xx: Correct logic for checking FAT or RAW MMCTom Rini2013-04-08-3/+17
| | | | | | | | | | | | | | | 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).

* arm: omap4: Fix SDRAM AUTO DETECTIONLokesh Vutla2013-04-08-18/+16
| | | | | | | | | | | | | | Commit "8602114 omap: emif: configure emif only when required" breaks SDRAM_AUTO_DETECTION. The issue is dmm_init() depends on emif_sizes[](SDRAM Auto detection) done in do_sdram_init(). The above commit moves dmm_init() above do_sdram_init() because of which dmm_init() uses uninitialized emif_sizes[]. So instead of using global emif_sizes[], get sdram details locally and calculate emif sizes. Reported-by: Michael Cashwell <mboards@prograde.net> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>

* omap2420-h4: Fix booting from NOR flashHunter, Jon2013-04-08-3/+3
| | | | | | | | | | | | | | | | The omap2420-h4 board is using a RAM based address as the linker location for code. This is causing several problems when attempting to run the latest u-boot code base on this board from flash. Update the default linker location for code to be in NOR flash. Please note that OMAP maps the NOR flash to address 0x08000000 by default and so use this as the default address for the NOR flash. Also remove legacy code that attempts to calculate where in flash the sdata structure, that holds the memory interface configuration data, is located. By changing the default linker location for code to flash this is no longer necessary. Signed-off-by: Jon Hunter <jon-hunter@ti.com>

| * 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".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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".
