A single motherboard could +host between 12 and 48 nodes, each with their own quad-core ARMv7 +processor, private DRAM and peripherals, connected through a high-bandwith +and low-latency "fabric" network. Multiple motherboards could be connected +together, to extend this fabric. + +For the purpose of U-Boot we just care about a single node, this can be +used as a single system, just using the fabric to connect to some Ethernet +network. Each node boots on its own, either from a local hard disk, or +via the network. + +The earlier ECX-1000 nodes ("Highbank") contain four ARM Cortex-A9 cores, +a Cortex-M3 system controller, three 10GBit/s MACs and five SATA +controllers. The DRAM is limited to 4GB. + +The later ECX-2000 nodes ("Midway") use four Cortex-A15 cores, alongside +two Cortex-A7 management cores, and support up to 32GB of DRAM, while +keeping the other peripherals. + +For the purpose of U-Boot those two SoCs are very similar, so we offer +one build target. The subtle differences are handled at runtime. +Calxeda as a company is long defunct, and the remaining systems are +considered legacy at this point. + +Bgilding U-Boot +--------------- +There is only one defconfig to cover both systems:: + + $ make highbank_defconfig + $ make + +This will create ``u-boot.bin``, which could become part of the firmware update +package, or could be chainloaded by the existing U-Boot, see below for more +details. + +Boot process +------------ +Upon powering up a node (which would be controlled by some BMC style +management controller on the motherboard), the system controller ("ECME") +would start and do some system initialisation (fabric registration, +DRAM init, clock setup). It would load the device tree binary, some secure +monitor code (``a9boot``/``a15boot``) and a U-Boot binary from SPI flash +into DRAM, then power up the actual application cores (ARM Cortex-A9/A15). +They would start executing ``a9boot``/``a15boot``, registering the PSCI SMC +handlers, then dropping into U-Boot, but in non-secure state (HYP mode on +the A15s). + +U-Boot would act as a mere loader, trying to find some ``boot.scr`` file on +the local hard disks, or reverting to PXE boot. + +Updating U-Boot +--------------- +The U-Boot binary is loaded from SPI flash, which is controlled exclusively +by the ECME. This can be reached via IPMI using the LANplus transport protocol. +Updating the SPI flash content requires vendor specific additions to the +IPMI protocol, support for which was never upstreamed to ipmitool or +FreeIPMI. Some older repositories for `ipmitool`_, the `pyipmi`_ library and +a Python `management script`_ to update the SPI flash can be found on Github. + +A simpler and safer way to get an up-to-date U-Boot running, is chainloading +it via the legacy U-Boot:: + + $ mkimage -A arm -O u-boot -T standalone -C none -a 0x8000 -e 0x8000 \ + -n U-Boot -d u-boot.bin u-boot-highbank.img + +Then load this image file, either from hard disk, or via TFTP, from the +existing U-Boot, and execute it with bootm:: + + => tftpboot 0x8000 u-boot-highbank.img + => bootm + +.. _`ipmitool`: https://github.com/Cynerva/ipmitool +.. _`pyipmi`: https://pypi.org/project/pyipmi/ +.. _`management script`: https://github.com/Cynerva/cxmanage diff --git a/doc/board/highbank/index.rst b/doc/board/highbank/index.rst new file mode 100644 index 0000000..b6975ca --- /dev/null +++ b/doc/board/highbank/index.rst @@ -0,0 +1,9 @@ +..
