54 bool "Enable AHB driver for NVIDIA Tegra SoCs"
57 Adds AHB configuration functionality for NVIDIA Tegra SoCs,
58 which controls AHB bus master arbitration and some
59 perfomance parameters(priority, prefech size).

109 Automatically determines which UART to use for low-level debug based
110 on the ODMDATA value. This value is part of the BCT, and is written
111 to the boot memory device using nvflash, or other flashing tool.
112 When bits 19:18 are 3, then bits 17:15 indicate which UART to use;
113 0/1/2/3/4 are UART A/B/C/D/E.
115 config TEGRA_DEBUG_UART_AUTO_SCRATCH
116 bool "Via UART scratch register"
118 Automatically determines which UART to use for low-level debug based
119 on the UART scratch register value. Some bootloaders put ASCII 'D'
120 in this register when they initialize their own console UART output.
121 Using this option allows the kernel to automatically pick the same
