* zynq: Fix elf header generationMichal Simek2014-02-13-0/+101
| | | | | | | | | | | | This patch is here because of: "arm: keep all sections in ELF file" (sha1: 47ed5dd031d7d2c587e6afd386e79ccec1a1b7f7) Our tools expect to have elf with only LOAD header. Without this fix also PHDR, INTERP and DYNAMIC headers are available in ELF. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* zynq: Use full tftpboot command instead of shortcut tftpMichal Simek2014-02-13-1/+1

* ARM: bcm2835: config.mk isn't neededStephen Warren2014-02-13-19/+0
| | | | | | | | | | | | | | | | | | The entries in config.mk were needed so that U-Boot could be built with an old version of the Raspberry Pi Foundation's toolchain. Without them, the build would error out with: ...-ld: error: .../libgcc.a(_bswapsi2.o) uses VFP register arguments, u-boot does not However, none of the 3 toolchains in the latest version of their tools.git, nor the Ubuntu/Linaro ARM compilers in at least Ubuntu Quantal or Saucy, need these options set in order to compile a working U-Boot. Hence, remove the options for simplicity. Reported-by: Tom Rini <trini@ti.com> Signed-off-by: Stephen Warren <swarren@wwwdotorg.org> Reviewed-by: Andreas Färber <afaerber@suse.de>
* ARM: rpi_b: set $fdtfile in default environmentStephen Warren2014-02-13-0/+1
| | | | | | | | | | | | | | U-Boot names the Raspberry Pi board rpi_b. This means that the common expression for DTB filename ${soc}-${board}.dtb expands to bcm2835-rpi_b.dtb. However, the DTB generated by the Linux kernel is bcm2835-rpi-b.dtb. Set $fdtfile in U-Boot's environment so that scripts look for the correct DTB filename. An alternative would be to rename the U-Boot board to rpi-b. However, that change would be far more invasive, and end up affecting users (i.e they'd have to change their U-Boot build commands).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tegra124's MMC controller is very similar to earlier SoC generations, and can be supported by the same driver. However, there are some non-backwards-compatible HW differences, and hence a new DT compatible value must be used to describe the HW. This patch updates the driver to support that new compatible value. That said, the HW differences are only relevant when enabling certain high-performance transfer modes. Since the driver is currently very simple and doesn't enable those modes, we don't actually need to address any of these HW differences in the code yet, hence the simple nature of this patch.

* | ARM: tegra: don't exceed AVP limits when configuring PLLPJimmy Zhang2014-02-03-87/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on the Tegra TRM, the system clock (which is the AVP clock) can run up to 275MHz. On power on, the default sytem clock source is set to PLLP_OUT0. In function clock_early_init(), PLLP_OUT0 will be set to 408MHz which is beyond system clock's upper limit. The fix is to set the system clock to CLK_M before initializing PLLP, and then switch back to PLLP_OUT4, which has an appropriate divider configured, after PLLP has been configured Implement this logic in new function tegra30_set_up_pllp(), which sets up PLLP and all PLLP_OUT* dividers, and handles the AVP clock switching. Remove the duplicate PLLP setup from pllx_set_rate() and adjust_pllp_out_freqs().

* | ARM: tegra: amend pmc.h for Tegra114+Stephen Warren2014-02-03-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tegra114 and later's PMC module removes the pwrgate_timer_on register and replaces it with a clamp_status register. Adjust pmc.h to reflect this, and update any code affected by the change. The cpu.c change in this patch was extracted from a much larger patch by Jimmy Zhang. The pmc.h change was written from scratch, but inspired by related changes made by Tom Warren. There could well be other differences in the PMC register set for chips after Tegra20/30. However, they don't affect the code in U-Boot at present, so I haven't attempted an exhaustive update of pmc.h.
