* arm: socfpga: rename socfpga_cyclone5 and socfpga_arria5 config filesDinh Nguyen2015-09-23-2/+2
| | | | | | | | | Rename the socfpga_cyclone5.h to socfpga_cyclone5_socdk.h, and socfpga_arria.h to socfpga_arria5_socdk.h. This matches the other SoCFPGA board config files. Suggested-by: Marek Vasut <marex@denx.de> Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com>
* ARM: tegra114: Clear IDDQ when enabling PLLCThierry Reding2015-09-16-0/+8
| | | | | | | | | | | | Enabling a PLL while IDDQ is high. The Linux kernel checks for this condition and warns about it verbosely, so while this seems to work fine, fix it up according to the programming guidelines provided in the Tegra K1 TRM (v02p), Section 5.3.8.1 ("PLLC and PLLC4 Startup Sequence"). The Tegra114 TRM doesn't contain this information, but the programming of PLLC is the same on Tegra114 and Tegra124.

* ARM: tegra: clk_m is the architected timer source clockThierry Reding2015-09-16-10/+8
| | | | | | | | | | | While clk_m and the oscillator run at the same frequencies on Tegra114 and Tegra124, clk_m is the proper source for the architected timer. On more recent Tegra generations, Tegra210 and later, both the oscillator and clk_m can run at different frequencies. clk_m will be divided down from the oscillator.

* ARM: tegra: Implement clk_mThierry Reding2015-09-16-2/+31
| | | | | | | | | | On currently supported SoCs, clk_m always runs at the same frequency as the oscillator input. However newer SoC generations such as Tegra210 no longer have that restriction. Prepare for that by separating clk_m from the oscillator clock and allow SoC code to override the clk_m rate.

* ARM: tegra: fix PLLP frequency calc on T210Stephen Warren2015-09-16-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | AFAIK, for all PLLs on all Tegra SoCs, the primary PLL output frequency is (input * m) / (n * p). However, PLLP's primary output (pllP_out0) on T210 is the VCO output, and divp is not applied. pllP_out2 does have divp applied. All other pllP_outN are divided down from pllP_out0. We only support pllP_out0 in U-Boot at the time of writing. Fix clock_get_rate() to handle this special case. This corrects the returned rate for PLLP to be 408MHz rather than 204MHz. In turn, this causes high enough dividers to be calculated for the various peripheral clocks that feed off of PLLP. Without this, some peripherals failed to operate correctly. For instance, one of my SD cards worked perfectly but an older (presumably slower) card could not be read. Note that prior to commit 722e000ccd72 "Tegra: PLL: use per-SoC pllinfo table instead of PLL_DIVM/N/P, etc.", the calculated PLL frequency was 816MHz since the wrong values were being extracted from the PLLP divider register. This caused overly large peripheral dividers to be calculated, which while wrong, didn't cause any correctness issues; things simply ran slower than they could.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This arch does not seem to be supported / used at all in the current U-Boot mainline source tree any more. So lets remove the core u8500 code and code that was only referenced by this platform. Please note that this patch also removes these config options: - CONFIG_PL011_SERIAL_RLCR - CONFIG_PL011_SERIAL_FLUSH_ON_INIT As they only seem to be referenced by u8500 based boards. Without any such board in the current code, these config option don't make sense any more. Lets remove them as well. If someone still wants to use this platform, then please send patches to re-enable support by adding at least one board that references this code.

This patch add the following: 1. Discard PHYS_SDRAM_SIZE from header file, use imx_ddr_size() 2. Introduce a macro is_mx6ul_9x9_evk using CONFIG_IS_ENABLED(TARGET_MX6UL_9X9_EVK) to avoid "#ifdef xxx" in non-SPL part. To SPL part, CONFIG_IS_ENABLED(TARGET_MX6UL_9X9_EVK) can not work, so still use "#ifdef CONFIG_TARGET_MX6UL_9X9_EVK" to differentiate with mx6ul_14x14_evk. And we have no way to dymaically checking this chip is 9x9 or 14x14. 3. mx6ul_9x9_evk use pfuze3000, so enabled POWER related configurations. POWER related configurations also effect for mx6ul_14x14_evk. But power_init_board implementation using 'if (is_mx6ul_9x9_evk())' to do initialization for mx6ul_9x9_evk, and do nothing for mx6ul_14x14_evk. 4. mx6ul_9x9_evk use lpddr2 with size 256MB, so add related SPL DRAM configurations. 5. Enable CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG and setting dtb file according to board_rev and board_name. 6.

Update the driver to fix the following: 1) When requesting GPI_xx and GPO_xx on port 3 (xx is the same number) the second call to "gpio_request" will return -EBUSY. 2) The status of GPO_xx pin report the status of the corresponding GPI_xx pin when using the "gpio status" command. 3) The gpio driver may setup the direction register for the wrong gpio when calling "gpio_direction_input" (GPI_xx) or "gpio_direction_output" (GPO_xx) on port 3; the call to the direction is require to use the "gpio status" command. The following change were done in the driver: 1) port3 GPI are cache in a separate 32 bits in the array. 2) port3 direction register written only for GPIO pins. 3) port3 GPO & GPIO (as output) are read using "p3_outp_state". 4) LPC32XX_GPI_P3_GRP updated to match the change.
