[U-Boot] [PATCHv4 0/9] Migrate NXP/Freescale Vybrid based boards to support pure DT
Changes since v3: - Add missing space in device tree. - Reorder the patchset to avoid broken state.
Changes since v2: - Split the patch for updating the license string. - Reorder the patchset to avoid broken state.
Changes since v1: - Update the license string in device tree's. - Update all lpuart's uart nodes in device tree. - Dropped *_dtb_defconfig and updated the default defconfig's with DT support. - Reordered defconfig's using defconfig via savedefconfig. - Use one patch to update all Vybrid based board defconfig's. - Dropped vybrid_gpio driver legacy code. Thanks! Stefan for pointing this. - Dropped the legacy way of enabling GPIO, UART and SPI on NXP/Freescale Vybrid based board's.
- Compile checked for vf610twr and pcm052 since I don't have access to such hardware at my end. Reviewer's and tester's welcome!

Let's go with pure DT solution for board's based on NXP/Freescale Vybrid platform.
- Merge the DT defconfig with non-DT defconfig for Toradex Colibri VF50/VF61 and drop the non-DT defconfig. - Update the legacy defconfigs for NXP/Freescale VF610 Tower Board with DT. - Update the legacy defconfigs for Phytec phyCORE-vybrid Board with DT.

Changes since v3:
- Add missing space in device tree.
- Reorder the patchset to avoid broken state.
Changes since v2:
- Split the patch for updating the license string.
- Reorder the patchset to avoid broken state.
Changes since v1:
Update the license string in device tree's.
Update all lpuart's uart nodes in device tree.
Dropped *_dtb_defconfig and updated the default defconfig's with DT support.
Reordered defconfig's using defconfig via savedefconfig.
Use one patch to update all Vybrid based board defconfig's.
Dropped vybrid_gpio driver legacy code. Thanks! Stefan for pointing this.
Dropped the legacy way of enabling GPIO, UART and SPI on NXP/Freescale Vybrid based board's.
Compile checked for vf610twr and pcm052 since I don't have access to such hardware at my end. Reviewer's and tester's welcome!
