50 depends on ARCH_TEGRA_2x_SOC
54 bool "Enable AHB driver for NVIDIA Tegra SoCs"
57 Adds AHB configuration functionality for NVIDIA Tegra SoCs,

65 depends on ARCH_TEGRA_2x_SOC
67 Support for nVidia Harmony development platform
71 depends on ARCH_TEGRA_2x_SOC
74 Support for the Kaen version of Seaboard
78 depends on ARCH_TEGRA_2x_SOC
80 Support for the Toshiba AC100/Dynabook AZ netbook
84 depends on ARCH_TEGRA_2x_SOC
86 Support for nVidia Seaboard development platform. It will
87 also be included for some of the derivative boards that
88 have large similarities with the seaboard design.

142 config TEGRA_DEBUG_UART_AUTO_ODMDATA
145 Automatically determines which UART to use for low-level debug based
146 on the ODMDATA value. This value is part of the BCT, and is written
147 to the boot memory device using nvflash, or other flashing tool.
148 When bits 19:18 are 3, then bits 17:15 indicate which UART to use;
149 0/1/2/3/4 are UART A/B/C/D/E.
151 config TEGRA_DEBUG_UART_AUTO_SCRATCH
152 bool "Via UART scratch register"
154 Automatically determines which UART to use for low-level debug based
155 on the UART scratch register value. Some bootloaders put ASCII 'D'
156 in this register when they initialize their own console UART output.
157 Using this option allows the kernel to automatically pick the same

166 Adds system DMA functionality for NVIDIA Tegra SoCs, used by
167 several Tegra device drivers
