2018-09-17x86: dts: edison: configure I2C#6 pinsGeorgii Staroselskii
Now that we have the pinctrl driver for Merrifield in place we can make use of it and set I2C#6 pins appropriately. Initial configuration came from the firmware. Which quite likely has been used in the phones, where that is not part of Atom peripheral, is in use. Thus we need to override the leftover.

2018-09-17x86: tangier: pinmux: add API to configure protected pinsGeorgii Staroselskii
This API is going to be used to configure some pins that are protected for simple modification. It's not a comprehensive pinctrl driver but can be turned into one when we need this in the future. Now it is planned to be used only in one place. So that's why I decided not to pollute the codebase with a full-blown pinctrl-merrifield nobody will use. This driver reads corresponding fields in DT and configures pins accordingly. The "protected" flag is used to distinguish configuration of SCU-owned pins from the ordinary ones. The code has been adapted from Linux work done by Andy Shevchenko in pinctrl-merrfifield.c Signed-off-by: Georgii Staroselskii <georgii.staroselskii@emlid.com> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> [bmeng: fix build warning] Signed-off-by: Bin Meng <bmeng.cn@gmail.com>

AM654 allows for booting from primary or backup boot media. Both media can be chosen individually based on switch settings. ROM looks for a valid image in primary boot media, if not found then looks in backup boot media. In order to pass this boot media information to boot loader, ROM stores a value at a particular address. Add support for reading this information and determining the boot media correctly.

2018-09-11arm: K3: Update _start instructionLokesh Vutla
On K3 family SoCs, once the ROM loads image on R5, M3 resets R5 and expects to start executing from 0x0. In order to handle this ROM updates the boot vector of R5 such that first 64 bytes of image load address are mapped to 0x0. In this case, it is SPL's responsibility to jump to the proper image location. So, update the PC with address of reset vector(like how other exception vectors are handled), instead of branching to reset.
