From eb222d1d7de5946501ed15c49f9d23bc05fc5a87 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Wed, 27 Mar 2013 09:37:02 +0000 Subject: [PATCH] ARM: tegra: support T33 SKU of Tegra30 Make U-Boot aware of the T33 SKU of Tegra30, and treat it identically to any other Tegra30. An alternative would be to simply remove the SKU checking from tegra_get_chip_type(); most use of the value most likely simply wants to know the current chip, not the specific SKU. Or, the function could be split into separate tegra_get_chip() and tegra_get_sku() for the cases where differentiation really is required. I wonder whether tegra_get_chip_type() should printf() whenever any unkown chip/SKU is found, although perhaps the function is called so early that the printf() wouldn't actually make it to the UART anyway.
