2021.11

Hart Software Services Release 2021.11

HSS Changes since last release

This tag brings several improvements to the Hart Software Services since 2021.08:

• Add support for MiV Inter-Hart Communications (IHC) module
• Add Bus-Error Unit monitor
• Unique serial ID for each USBD block device
• skip-opensbi added to booting and the hss-payload-generator to allow SMP Bare Metal
• Remove unused eNVM driver
• Sanity checks on L2LIM size

This tag introduces new hss-payload-generator binaries (v0.99.26).

If using the default configuration (CONFIG_HSS_USE_IHC=y / CONFIG_USE_IHC=y / CONFIG_SERVICE_OPENSBI_IHC=y) this tag depends upon the PolarFire® SoC Icicle Kit Reference Design v2021.11 (which includes IHC).

  • Extra debug commands have been added
• DEFLATE: Adding support for eNVM wrapper to decompress HSS from eNVM to L2LIM
• Enables full 2GiB memory test
• Adds sample def_config files for no-logo/quiet boot etc.

• Add support for booting directly from SPI flash
• Adds hooks for configuring PMPs from Libero

2021.04

Hart Software Services Release 2021.04

Changes since last release

This tag brings several improvements to the Hart Software Services since 2020.12:

• Reserving first 256-bytes of eNVM to facilitate introduction of secure boot (requires SoftConsole 6.6 / Libero 2021.01 or later);
• Enable RMW on DDRC (to address issue with 0-byte AXI transfers from fabric to DDR);
• Changes default eMMC at 1.8v (requires board jumpers J34/J43 to change to select 1.8v), including higher speeds and faster booting;
• Fixes bug in error checking on eMMC;
• Updated MPFS_HAL to v1.8.116, which includes DDRC fixes and hooks for AMP APB;
• Memory reconfigured - 256KiB lower DDR reserved for non-cached/non-cached write-combine buffers for custom fabric design purposes:
  • 768MiB lower DDR region (32-bit addressable, 0x8000'0000 to 0xAFFF'FFFF)
  • 1GiB upper DDR region (64-bit addressable, 0x10'0000'0000 to 0x10'3FFF'FFFF)
  • 128MiB Non-cached region (aliases at lower 32-bit address 0xC000'0000 and 64-bit address 0x14'0000'0000)
  • 128MiB Non-cached Write Combine Region (aliased at lower 32-bit address 0xD000'0000 and 64-bit address 0x18'0000'0000)
  • Updated Icicle Kit design MSS configuration description XML for 2021.04 release;
• Allow programming of eNVM directly from make, once build is complete ('make program' - requires SoftConsole 6.6 / Libero 2021.01 or later);
• Updated MPFS Configuration Generator tool to removing trailing spaces in generated code

eMMC 1.8V jumpers

Please ensure both J43 and J34 are in positions 2-3 after updating your Icicle Kit to the 2021.04 Icicle Kit Reference Design.

2020.12

This tag brings several improvements to the Hart Software Services since 2020.11:

1. Modified switching between SD card and eMMC to use an FPGA fabric register instead of MSS GPIOs.
   This prevents SD card/eMMC mux glitching when GPIOs are re-initialized in later boot stages.
2. Enabled reset input from FPGA fabric.
   This allows push button reset with suitable FPGA designs. For example, this allows using push button SW4 to reset the Icicle Kit when using the Icicle Kit Reference Design 2020.12 or later.
3. Added clearing of pending PCIe interrupts before releasing execution of next boot stage.
   This prevents PCIe hanging with Linux kernel 5.10.
4. Added support for consuming MSS configurations generated by the Libero 12.6 MSS Configurator

2020.11

This tag brings several improvements to the Hart Software Services since 2020.10:

1. Custom boot flows added:
   To use prominent open-source bootloaders (such as U-Boot SPL, Coreboot, and EDK2) on PolarFire boards, we need a mechanism to boot all HARTs (both E51 and U54s) at same entry point in M-mode. To read more see commit 2cd45c9 from @avpatel.

2. MPU fixes in commit 6a2960e

3. Allowing both eMMC and SD card at the same time:
   The HSS can now switch between SD cards and eMMC automatically as a startup source, this update also requires the Icicle Kit Reference Design Tag 2020.11. See commits:
