Board-specific code lacked a Kconfig file defining CONFIG_SYS_BOARD, CONFIG_SYS_VENDOR, etc - patch 1 fixes that.
I was very pleased to notice the recent changes in PCI/USB code fixed xhci-pci functionality on DS414, so patch 2 enables XHCI support in defconfig.
Adjusting DS109 atags code for DS414 allowed to successfully boot vendor Linux, so I went ahead and generalized the code to support both boards in patch 3.
Patch 4 introduces a misc_init_r() routine populating environment from Synology's special flash partition if appropriate - less manual work for users and no need for random MAC address fallback anymore.
Patch 6 extends the default environment by a command to update u-boot via tftp.
Phil Sutter (5): ds414: Add a Kconfig defining some strings configs: ds414: Enable XHCI_PCI by default board/Synology: Unify legacy kernel support ds414: Auto-populate env if appropriate ds414: Add sample u-boot update command
