The section +alignment was kept in sync by introducing aligment that should be +greater or equal to the actual section alignment. + +This patch compute the load memory addresses of the sections so that +the layout is the same as the virtual memory addresses. + +Signed-off-by: Sylvain Gault <sylvain.gault@gmail.com> +Tested-by: poma <pomidorabelisima@gmail.com> +Signed-off-by: Paulo Alcantara <pcacjr@zytor.com> +--- + core/i386/syslinux.ld | 63 ++++++++++--------------------------------------- + core/x86_64/syslinux.ld | 63 ++++++++++--------------------------------------- + 2 files changed, 24 insertions(+), 102 deletions(-) + +diff --git a/core/i386/syslinux.ld b/core/i386/syslinux.ld +index 7390451..92b75b1 100644 +--- a/core/i386/syslinux.ld ++++ b/core/i386/syslinux.ld +@@ -255,10 +255,9 @@ SECTIONS + . = 0x100000;
