Hello,
This patchset adds initial board support for iMX8QXP AI_ML board
from Einfochips. This board is one of the Consumer Edition and AI
boards of the 96Boards family.
This initial supports contains following peripherals which are tested and
known to work:
1. Debug serial via UART2
2. SD card
3. Ethernet
Thanks,
Mani
Note: This patchset depends on the below cleanup patches submitted:
[U-Boot,1/2] arm: imx8: factor out uart init code
[U-Boot,2/2] arm: imx8: don't duplicate build_info()
Changes in v4:
* Incorporated review comments from Fabio.
Changes in v3:
* Incorporated review comments from Fabio. Major change is switching to
distro_boot.
* Added Reviewed-by tag from Peng Fan.
Changes in v2:
* Rebased the patches on top of following patches:
[U-Boot,1/2] arm: imx8: factor out uart init code
[U-Boot,2/2] arm: imx8: don't duplicate build_info()

When initially upstreaming i.MX8 to U-Boot, the dts was reused from downstream, because Linux upstream still not have that device tree. When Linux i.MX8 device tree stable, we need to migrate to use Linux dts without fsl- prefix. Currently It is under some restructure for long time and missed i.MX8QM support.

But, yeah I can remove it now and add once needed. The general rule is to avoid adding any dead (i.e. not used) code to the main line. The practical reason for it is to have the code base as small as possible. Moreover, the patch, which adds this board is rather large, so in that way we make it smaller. This code shall be added when you introduce the GPIO needed for this board. > > > > +#if IS_ENABLED(CONFIG_FEC_MXC) > > > +#include <miiphy.h> > > > + > > > +int board_phy_config(struct phy_device *phydev) > > > +{ > > > + phy_write(phydev, MDIO_DEVAD_NONE, 0x1d, 0x1f); > > > + phy_write(phydev, MDIO_DEVAD_NONE, 0x1e, 0x8); > > > + > > > + phy_write(phydev, MDIO_DEVAD_NONE, 0x1d, 0x05); > > > + phy_write(phydev, MDIO_DEVAD_NONE, 0x1e, 0x100); > > > + > > > + if (phydev->drv->config) > > > + phydev->drv->config(phydev); > > > + > > > + return 0; > > > +} > > > +#endif > > > + > > > +int checkboard(void) > > > +{ > > > + puts("Board: iMX8QXP AI_ML\n"); > > > + > > > + build_info(); > > > + print_bootinfo(); > > > + > > > + return 0; > > > +} > > > + > > > +int board_init(void) > > > +{ > > > + board_gpio_init(); > > > + > > > + return 0; > > > +} > > > > Here you call the empty board_gpio_init(). > > > > As per above comment, I'll remove it. > > > > + > > > +/* Board specific reset that is system reset */ > > > + > > > +void reset_cpu(ulong addr) > > > +{ > > > + /* TODO */ > > > +} > > > > Maybe you could use the SYSRESET driver from the outset?
