Everyone: Picking up where Sascha left off, this is the next version of the patchset that adds support for i.MX8MQ EVK board. This patchest is also availible at: https://github.com/ndreys/barebox/tree/imx8m-support-v6 Changes since [v6]: - Patchset rebased on latest master, so it is now down to 10 patches - <linux/iopoll.h> support in PBL is now done by stubbing out get_time_ns() and is_timeout() in clock.h - Additional speeling fixes Changes since [v4]: - Fix a critical OCOTP bug (missing .format_mac in "ARM: i.MX: ocotp: Add i.MX8MQ support") introduced in v3 and was exposed by defconfig change in v4 - Minor spelling/gramatical fixes in various commits and commit messages Changes since [v3]: - Timeout/delay functions were moved into lib/ instead of being inline in order to avoid image size increase. - Imx-image chages were reworked to fix regression identified by Alexander Kurz in [regression1] - Minor fix to "clock: Use udelay() to implement mdelay()" (33/54) to prevent 32-bit ARM EABI toolchain from issuing a call to unsigned long division helper - Imx_v8_defconfig was modified to be as close to imx_v7_defconfig as possible. Removed options: CONFIG_PBL_CONSOLE=y CONFIG_CONSOLE_RATP=y Added options: CONFIG_CONSOLE_ACTIVATE_NONE=y CONFIG_CMD_DHCP=y CONFIG_CMD_MIITOOL=y CONFIG_CMD_PING=y CONFIG_CMD_I2C=y CONFIG_NET=y CONFIG_NET_NETCONSOLE=y CONFIG_NET_RESOLV=y CONFIG_DRIVER_NET_FEC_IMX=y CONFIG_I2C=y CONFIG_I2C_IMX=y CONFIG_FS_TFTP=y CONFIG_FS_NFS=y Changes since [v2]: - i.MX8 specific eSDHC bootstrap code code fixed to function correctly with high capacity SD cards - DDR PHY firmware converted to use Sascha's firmware framework and be SoC specific (can be shared among different boards) - DDR register definitions moved to imx8-ddrc.h as well as cleaned up to contain only constants that are being used - Incorporated imx-image i.MX8 work done by Sascha as well as extend it to create valid AArch64 header - Patchset is rebase on latest 'next' branch to accomodate recent OCOTP changes Changes since [v1]: - The patchset now allows building 1st stage bootloader that can be progammed on SD card and booted standalone Currently out of scope of this patch (not tested or documented, will be coming in a follow up series): - Integration of ARM Trusted Firmware - Booting Linux kernel Current assumptions (all subject to change, but listed below to be explicit): - DDR initialization code is auto-generated by i.MX8M DDR Tool and used as close to as-is as possible. Feedback is wellcome!
