ARM: tegra: re-calculate the LP1 data for Tegra30/114
Browse files Browse the repository at this point in the history
This patch re-calculates the LP1 data of tegra30/114_sdram_pad_address
to base on its label not rely on others. This can make easier to
maintain if some other Tegra chips keep re-using these codes in the
future. And change the name of tegra30_sdram_pad_save to
tegra_sdram_pad_save to make it more common to other chips.
