Dario Binacchi c85312affd configs/stm32f429_disco: fix kernel bootup 
The kernel generated by the configuration for the STM32f429-discovery
board is buggy:

Fixes:

Inspired by commit a3e3d9c198 ("configs/stm32f469_disco_xip_defconfig:
alternative defconfig for XIP"), update the stm32f429_disco_defconfig
configuration to use a newer kernel. Current setup kernel + rootfs fits
in 1.6MB on-chip flash memory.

The kernel has been moved to new flash bank due to growth of dtb size.

Remove upstream patch.

For better binary size optimization gcc LTO is turned on.

README 

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on OFTC IRC.
