From: Hauke Mehrtens Date: Tue, 10 May 2011 21:31:33 +0000 (+0200) Subject: MIPS: BCM47xx: Extend the filling of SPROM from NVRAM X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=41790fd51f71f3744a5d142cc5369eebab8817a0;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git MIPS: BCM47xx: Extend the filling of SPROM from NVRAM Some members of the struct ssb_sprom where not filled with data available in the NVRAM. Some attribute names in the NVRAM changed from SPROM version 3 to version 4. This patch was done by analyzing the the pci sprom parser in the ssb code and some open source parts of the braodcom wireless driver used on embedded devices.
