Do not keep NOTES section align in proper location. 'readelf' shows that 'NOTE' is placed in wrong location which is out of virtual and physical load addresses. Section Headers: [Nr] Name Type Addr Off Size ES Flg Lk Inf Al [ 1] .note.gnu.build-i NOTE 00000000 001000 000024 00 A 0 0 4 [ 2] .text PROGBITS c0000000 002000 284570 00 AX 0 0 16 [ 3] __fdt_blob PROGBITS c0284570 286570 008000 00 A 0 0 1 Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align LOAD 0x001000 0x00000000 0x00000000 0x00024 0x00024 R 0x1000 LOAD 0x002000 0xc0000000 0x08000000 0x315428 0x316000 RWE 0x1000 This patch move 'NOTE' section to the correct location. Checked with: "ARM: 6740/1: Place correctly notes section in the linker script" (sha1:dc810efb0c) and "[S390] incorrect note program header" (sha1:7a2512b744) Signed-off-by: Michal Simek <michal.simek@xilinx.com>
