From e5a9a4076f1fb9fb9ce53c2aec32422073bbc66a Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 18 Oct 2013 13:04:42 -0500 Subject: [PATCH] pxe: fix handling of absolute paths pxelinux and syslinux differ in their handling of absolute paths in menu files. A pxelinux path is aways prepended with the bootfile path while syslinux allows for absolute paths. u-boot was always treating a leading / as an absolute path breaking some pxelinux setups. Fix this by adding a flag to distinguish pxelinux vs. syslinux behavior.
