configs/stm32f469_disco_xip_defconfig: alternative defconfig for XIP Update STM32F469-disco configuration files to operate with new kernel. Result of make tinyconfig was taken as a starting point to fit kernel into flash memory. Current setup kernel + rootfs fits in 1.6MB on-chip flash memory Fixes: - Move kernel to new flash bank due to growth of dtb size - Fix kernel start address in bootloader - Remove outdated path which doesn't affect normal operation mode For better binary size optimization gcc LTO is turned on. Signed-off-by: Yauheni Saldatsenka <eugentoo@gmail.com> [Arnout: - squash 3 patches into 1; - remove unused dts file; - move linux/linux.config to linux-xip.config; - add a sentence to readme to say SD card is not needed. ] Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>

configs/*: use BR2_ENABLE_LTO to enable LTO instead of BR2_GCC_ENABLE_LTO BR2_GCC_ENABLE_LTO only enables LTO in the toolchain, not in packages. Use BR2_ENABLE_LTO instead to enable it in packages as well. Note that BR2_GCC_ENABLE_LTO is currently non-functional (LTO is still enabled in the toolchain even if it's not set), so we *do* have LTO available in the toolchain. Note that the option has no effect at all on these defconfigs anyway, since they don't contain any package that is affected by the BR2_ENABLE_LTO option. Still, it makes sense to enable it for these really memory-constrained targets for when packages are added.

configs/stm32f469_xip_disco: fix kernel bootup The current configuration fails to boot on the stm32f469-disco board. Make it bootable again by reverting the DRAM patches. Also change the kernel load address from 0x8010000 to 0x800C000 to allocate more space to the kernel, since 32kB for the device tree is enough. Also clean up the rootfs a bit with the common stm32-post-build.sh script.

boot/afboot-stm32: upgrade version Newer versions of the kernel generate device trees that are not storable in a single 16kB sector. In these cases the kernel load address must be changed. The commit 2e499dcff3ef ("Add possibility to use custom kernel load address") adds the possibility to override the default (0x08008000) kernel load address. This also required changes to the stm32f429_disco_defconfig and stm32f469_disco_xip_defconfig configurations. Patching is no longer needed. Also update whitespaces in hash file (2 spaces).
