This series adds support for the Intel Minnowboard Max (called Minnowmax for short). Along the way a few refactors and additions are made:
- The Intel Firmware Support Package support is moved from queensbay to a common location - PCI support for XHCI is added - A few tweaks are made to the PCI support - Support for the debug UART (early debug output) is provided - The microcode tool now also supports reading in header files
This board has been lightly tested. The following seem to work:
- USB2 on the blue port (not USB3), e.g. for keyboard - Ethernet - HDMI out and console - UART - uSD card - SPI
SATA is detected but I have not attached a drive to try it. USB3 shows signs of life but does not detect a USB stick, and crashes when trying to use a USB Ethernet adaptor.
For SPI some parts cannot be read and others cannot be written. This seems to be a feature of the Intel hardware configuration. It may be possible to fix this using the SPI registers but I cannot work out how / lost interest trying. So far, addresses from 500000 to 700000 can be used.
I have not tried the ICH GPIO driver but it likely needs work before it will function. I2C is not supported as there is currently no U-Boot driver for this.
The zboot command can be used to start a bzImage kernel. Verified boot is supported - use mkimage to sign images as described in this walk-through: doc/uImage.FIT/beaglebone_vboot.txt
Boot time is grim: - 1423ms to set up display (Intel FSP) - 454ms to scan AHCI (when no devices are connected) - ~1000ms to power up and start cache-as-RAM init (Intel FSP) (this is not benchmarked, may be inaccurate) - ~950ms to set up memory and initial machine configuration (Intel FSP) (this is not benchmarked, may be inaccurate)
So it takes over 4 seconds to get to booting a kernel.
Implementing the Memory Reference Code (MRC) cache should improve this slightly (perhaps a reduction of 500-1000ms). This cache is implemented for ivybridge so that code needs to be moved into a generic x86 directory and plumbed into the FSP code. This has not been done in this series. Also the video and SATA/AHCI can be disabled if preferred.
It is also possible to run as a coreboot payload. See the instructions in README.x86 for this. In this case video does not work since coreboot does not pass through the VESA display information.
To support the single-core 1GB variant, changes would need to be made to arch/x86/cpu/baytrail/fsp_configs.c to select different values for the memory. The microcode update may need to change also.
This series is available at u-boot-x86 branch minnow-working.
