Changes in the lsi-v2013.01.01 Branch U-Boot 5.8.1.87 Changes • Revert “Changes for ARM errata 833469 and 834769 (CCN-504)”. • Update the default peripheral memory access settings. • Backport a patch to avoid infinite loops when attempting to read corrupted ext4 file systems. • Revert the commit included in 5.8.1.73 that eliminated the watchdog reset call in udelay(). This was originally included to handle the corrupt ext4 file system problem now solved by the backport mentioned above.

U-Boot 5.8.1.86 Changes • Changes for ARM errata 833469 and 834769 (CCN-504). When flushing the L3 cache, switcth the state to OFF and then to FULL instead of to SFONLY and then to FULL.

U-Boot 5.8.1.85 Changes • When using EIOA to boot, ‘macspeed=auto’ now works for GMAC ports. • Allow builds with either gcc 4 or gcc 5. • Outer cache functions are now written in assembler so they don’t use the stack.

U-Boot 5.8.1.84 Changes • Add a define to select which method of redundancy gets used when updating the parameters.

U-Boot 5.8.1.83 Changes • Update the unused parameters to avoid corrupting the parameters in use. • Indicate write errors, if they occur, when updating the parameters.

U-Boot 5.8.1.82 Changes • Only update the DDR settings in the parameters once, not every boot.

1

U-Boot 5.8.1.81 Changes • Add a watchdog update while running the MBIST.

U-Boot 5.8.1.80 Changes • Enabled Dynamic ODT in the DDR Retention Case. • Allow Flush Cache with End Address of 0xffffffff. • Revert the fixes to allow building with gcc 5.x, those changes break building with 4.x.

U-Boot 5.8.1.79 Changes • Fixes to allow building with gcc 5.x.

U-Boot 5.8.1.78 Changes • Revert the previous change to run LSM uncached. Instead, clear the HN-I errors before jumping to Linux. • Update the ssp driver transfer function to avoid a failure that is still under investigation.

U-Boot 5.8.1.77 Changes • SPL Linker map updates. – The page table was overlapping the BSS. – Available LSM was wrong based on the stack pointer.

U-Boot 5.8.1.76 Changes • In the MMU, make LSM uncached in the SPL. • Clean up printf() formatting in system memory initialization.

U-Boot 5.8.1.75 Changes • Update SMEM initialization to set the SRT bit in the DRAM MR2 register when ‘highTemperature’ is set in the parameters.

2

U-Boot 5.8.1.74 Changes • Don’t set ccn_qos_rni6_s0 in simulation.

U-Boot 5.8.1.73 Changes • Add the option, on by default, to leave the L3 cache in SFONLY mode. This is a work-around for occasionaly problems noticed when booting Linux. Make sure to get a version of Linux that re-enables the L3. • Don’t call the watchdog reset function in udelay(). • If ccn_qos_rni6_s0 is not set in the U-Boot environment, use a default value of 0x00cc000c. The default is defined in include/configs/axxia-arm.h. • Fix compile errors when DEBUG is defined. Only errors in Axxia specific code are fixed.

U-Boot 5.8.1.72 Changes • Removed SBB lockup test code that got checked in by mistake.

U-Boot 5.8.1.71 Changes • Corrected the sbb command return codes.

U-Boot 5.8.1.70 Changes • QoS support for AXI priority. If ccn_qos_rni6_s0 is set in the U-Boot environment, so_qos_control will be set to that value. • Updated the sbb command messages and error handling. In the previous version, an unsigned, and optionally unencrypted, image would boot with secure boot enabled. • PCIe speed change and enumeration now only applies when in root complex mode.

U-Boot 5.8.1.69 Changes • Make ‘sbb verify’ pass for all images when secure boot is disabled.

3

U-Boot 5.8.1.68 Changes • Work-around when using the SBB to validated images. To avoid lockups, the ‘aux_ctl’ register needs to be set to 0x9 while the SBB is validating images. • Now reads the CNTPCT value correctly In the work-around for ARM 811981. • Added support for SRIO 16 bit transport ID. Controlled by the parameter file.

U-Boot 5.8.1.67 Changes • Updated defines related to memory usage, and added comments. See include/configs/axxia-arm.h. • Calculate the size of secure images before reading them from flash. • New API for axxia_hybrid_mbist(). • Power down unused serdes channels. NOTE: To Power Down Unused Serdes Channels HSS5 & HSS6 lanes can be powered down via the following new PCIe/SRIO SPL parameter fields. Note that these new SPL parameter fields are not supported by the ASE hardware configuration editor yet. Support for these new fields will be provided in a forthcoming (newer than 1.2.12.110) ASE release. Monitor the ASE README for notification of feature availability. Prior to ASE support, HSS lane power-down can be enabled by hand-editing the ASE generated SPL parameter file. The current ASE hard-codes these PCIe/SRIO fields to 0. Therefore, legacy behavior is maintained when using a new U-Boot SPL with an SPL parameter file generated by current ASE software. PCIe/SRIO -
