Contact: Peter De Schrijver <>
Description: read-only access to the efuses on Tegra20, Tegra30, Tegra114
and Tegra124 SoC's from NVIDIA. The efuses contain write once
data programmed at the factory. The data is layed out in 32bit
words in LSB first format. Each bit represents a single value
as decoded from the fuse registers. Bits order/assignment
exactly matches the HW registers, including any unused bits.
Users: any user space application which wants to read the efuses on
Tegra SoC's
