From ffd8ca18cc292c8dd7b7d7df2d4c605f281bede1 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Tue, 19 Feb 2019 18:52:35 +0100 Subject: [PATCH] apm821xx: speed up ath9k-caldata extraction Reading and writing to and from flash storage is slow and currently, the ath10kcal_extract() scripts are even more at an disadvantage because they use a block size of 1 to be able skip. This patch reworks the extraction scripts to be much faster and efficient by reading and writing the calibration data in possibly one big block.
