From a2cd076b7f5ad3017fc8a2b22687cd58d02e85db Mon Sep 17 00:00:00 2001 From: =?utf8?q?Pali=20Roh=C3=A1r?= Date: Sat, 21 Jan 2023 13:59:20 +0100 Subject: [PATCH] cmd: mvebu/bubt: Fix parsing SATA kwbimage MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Despite the official specification, Marvell BootROM does not interpret srcaddr from SATA image as number of sectors the beginning of the hard drive, but as number of sectors relative to the main header. Reject invalid and accept valid SATA images.
