* Tegra: P2571: Clean up config fileTom Warren2015-08-051-6/+1
| | | | | | | Removed NS16550_COM1 #define, not used since there's no SPL for T210 Also changed the number of USB controllers to 1 as only USBD is used. Signed-off-by: Tom Warren <twarren@nvidia.com>

| | | | | | | | | | | All T114+ Tegra boards should be using the Kconfig TEGRA114_SPI switch. Remove it from include/config and put it into defconfig. Also removed unused TEGRA114_SPI_CTRLS from T114+ configs. All Tegra SoCs build OK with this change. Signed-off-by: Tom Warren <twarren@nvidia.com>
* Tegra: PLL: use per-SoC pllinfo table instead of PLL_DIVM/N/P, etc.Tom Warren2015-08-0512-174/+285
| | | | | | | | | | | | | Added PLL variables (dividers mask/shift, lock enable/detect, etc.) to new pllinfo struct for each Soc/PLL. PLLA/C/D/E/M/P/U/X. Used pllinfo struct in all clock functions, validated on T210. Should be equivalent to prior code on T124/114/30/20. Thanks to Marcel Ziswiler for corrections to the T20/T30 values.

* Tegra: clocks: Add 38.4MHz OSC support for T210 useTom Warren2015-08-055-11/+42
| | | | | | | | | | | | | | | Added 38.4MHz/48MHz entries to pll_x_table for CPU PLL. Needs to be measured - should be close to 700MHz (1.4G/2). Note that some freqs aren't in the PLLU table in T210 TRM (13, 26MHz), so I used the 12MHz table entry for them. They shouldn't be selected since they're not viable T210 OSC freqs. Since there are now 2 new OSC defines, all tables (pll_x_table, PLLU) had to increase by two entries, but since 38.4/48MHz are not viable osc freqs on T20/30/114, etc, they're just set to 0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is useful to be able to load U-Boot onto a board even if is it already running EFI. This can allow access to the U-Boot command interface, flexible booting options and easier development. The easiest way to do this is to build U-Boot as a binary blob and have an EFI stub copy it into RAM. Add support for this feature, targeting 32-bit initially. Also add a way to detect when U-Boot has been loaded via a stub. This goes in common.h since it needs to be widely available so that we avoid redoing initialisation that should be skipped.
