From 0649fb2f6c7e1bea138769ecc2ec8dc17ae98044 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sun, 31 Oct 2010 05:24:36 +0100 Subject: ADIv5: Introduce function to detect ROM Table location This patch adds function called "dap_detect_debug_base()", which should be called to get location of the ROM Table. By walking ROM Table, it's possible to discover the location of DAP. Sadly, some CPUs misreport this value, therefore I had to introduce an fixup table, which will be used in case such CPU is detected.
