2013-04-15Tegra: Split tegra_get_chip_type() into soc & sku funcsTom Warren
As suggested by Stephen Warren, use tegra_get_chip() to return the pure CHIPID for a Tegra SoC (i.e. 0x20 for Tegra20, 0x30 for Tegra30, etc.) and rename tegra_get_chip_type() to reflect its true function, i.e. tegra_get_chip_sku(), which returns an ID like TEGRA_SOC_T25, TEGRA_SOC_T33, etc. Signed-off-by: Tom Warren <twarren@nvidia.com> Reviewed-by: Stephen Warren <swarren@nvidia.com>
2013-04-15Tegra114: Initialize System Counter (TSC) with osc frequencyTom Warren
T114 needs the SYSCTR0 counter initialized so the TSC can be read by the kernel. Do it in the bootloader since it's a write-once deal (secure/non-secure mode dependent). Signed-off-by: Tom Warren <twarren@nvidia.com> Reviewed-by: Stephen Warren <swarren@nvidia.com>
2013-04-15Tegra: Configure L2 cache control reg properly.Tom Warren
Without this change, kernel fails at calling function cache_clean_flush during kernel early boot. Aprocryphally, intended for T114 only, so I check for a T114 SoC. Works (i.e. dalmore 3.8 kernel now starts printing to console). Signed-off-by: Tom Warren <twarren@nvidia.com>
2013-04-15ARM: tegra: support T33 SKU of Tegra30Stephen Warren
Make U-Boot aware of the T33 SKU of Tegra30, and treat it identically to any other Tegra30. An alternative would be to simply remove the SKU checking from tegra_get_chip_type(); most use of the value most likely simply wants to know the current chip, not the specific SKU. Or, the function could be split into separate tegra_get_chip() and tegra_get_sku() for the cases where differentiation really is required. I wonder whether tegra_get_chip_type() should printf() whenever any unkown chip/SKU is found, although perhaps the function is called so early that the printf() wouldn't actually make it to the UART anyway.

2013-04-13spi: mxc_spi: Set master mode for all channelsFabio Estevam
The glitch in the SPI clock line, which commit 3cea335c34 (spi: mxc_spi: Fix spi clock glitch durant reset) solved, is back now and itwas re-introduced by commit d36b39bf0d (spi: mxc_spi: Fix ECSPI reset handling). Actually the glitch is happening due to always toggling between slave mode and master mode by configuring the CHANNEL_MODE bits in this reset function. Since the spi driver only supports master mode, set the mode for all channels always to master mode in order to have a stable, "glitch-free" SPI clock line.

2013-04-08OMAP3/4/5/AM33xx: Correct logic for checking FAT or RAW MMCTom Rini
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).

2013-04-08arm: omap4: Fix SDRAM AUTO DETECTIONLokesh Vutla
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>
2013-04-08omap2420-h4: Fix booting from NOR flashHunter, Jon
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>
