[U-Boot] [RFC][PATCH 3/3] Add board support for the eXMeritus HWW-1U-1A devices

Kyle Moffett Kyle.D.Moffett at boeing.com
Mon Aug 30 20:24:53 CEST 2010


The eXMeritus HWW-1U-1A unit is a DO-160-certified 13lb 1U chassis
with 3 independent TEMPEST zones.  Two independent P2020 computers may
be found inside each zone.  Complete hardware support is included.

High-level hardware overview:
  * DO-160 certified for passenger aircraft (noncritical)
  * TEMPEST ceritified for RED/BLACK separation
  * 3 zones per chassis, 2 computers per zone (total of 6)
  * Dual-core 1.066GHz P2020 per computer
  * One 2GB DDR2 SO-RDIMM module per computer (upgradable to 4GB)
  * Removable 80GB or 160GB Intel X18-M SSD per computer
  * Front-accessible dual-port E1000E per computer
  * Front-accessible serial console per computer
  * Front-accessible USB port per computer
  * Internal Gigabit crossover within each TEMPEST zone
  * Internal unidirectional fiber links across TEMPEST zones
  * Battery-backed DS1339 I2C RTC on each CPU.

Combined, each 13lb 1U chassis contains 12GB RAM, 12 cores @ 1.066GHz,
12 front-accessible Gigabit Ethernet ports and 960GB of solid-state
storage with a total power consumption of ~200W.

Additional notes:
  * SPD detection is only known to work with the DO-160-certified DIMMs

  * A U-Boot built with 36-bit address-space seems to work, but I don't
    yet have a usable 36-bit kernel or DTB, so it's mostly untested.

  * CPU reset is a little quirky due to hardware misfeature, see the
    extensive comments in the board_reset_r() function in hww-1u-1a.c

+ * Unfortunately we have a bit of a problem with our reset line wiring on the

+ *
+ * Specifically the "CPU A" reset controls all of the PCI devices on the
+ * IO/backplane card, which means ethernet and SATA controllers for both
+ * CPU A *and* CPU B.
+ *
+ * This is somewhat of a problem if the CPUs are reset independently... CPU B
+ * might fail to come up because his PCI devices are confused, or CPU B might
+ * die because CPU A just reset the SATA controller for his root filesystem.
+ *
+ * Since in practice the CPUs never need to reboot independently we will go
+ * ahead and require GPIO cross-communication between them before either one
+ * will reset.
+ *
+ * The communication protocol uses GPIOs 4-7 on the PCA9554 GPIO expander
+ * found on I2C-2 at address 0x3f.  CPU A uses 4,5 as TX and 6,7 as RX; for
+ * CPU B we use the exact opposite.
+ *
+ * The GPIOs initialize as inputs during poweron, and are pulled high; the
+ * PCA9554 expanders will maintain valid outputs over soft-reset allowing for
+ * reliable operation.
+ *
+ * To avoid duplication, we will assign names to the GPIOs:
+ *            ,---------------------------------------.
+ *            |  GPIO4  |  GPIO5  |  GPIO6  |  GPIO7  |

+ *  |---------|---------|---------|---------|---------|
+ *  |  CPU B  |   rx1   |   rx2   |   tx1   |   tx2   |
+ *  `-------------------------------------------------'
+ *
+ * The state machine for each CPU is below.  In simplistic terms, each CPU
+ * waits until the other has cleared its GPIOs, then cause a tx1 high=>low
+ * transition.  Upon seeing the other CPU do the same, it will perform a
+ * tx2 high=>low transition and again wait.
+ *
+ * Once both CPUs have performed and seen both transitions, they will each
+ * set tx1 high (to create an "invalid" state) and then reset.
