DM355/DM644x Linux Support Package (LSP) 1.20 Updates

Linux Support Package 1.20 contains board utilities, drivers, examples and documentation for DMSoCs DM355 and DM644x. The LSP 1.20 Driver update provides new driver features and improved entitlement to peripheral capabilities for the MontaVista Linux kernel on DM355 and DM644x.

The latest version of LSP 1.20 product is 01.20.01.004. This is the Production Release plus Patch Level 14 version of LSP 1.20 based on demonstration version of MontaVista Linux Professional Edition 4.0.1. The kernel has been compiled with MontaVista Pro 4.0.1 toolchain based on GCC 3.4.3.

For DM644x Linux users, LSP 1.20 contains a merging of TI patches (TI Patch Level 49 on LSP 1.10) and MontaVista patches, creating a united patched kernel tree. The latest MonstaVista LSP patches to be applied can be found under the "mvl_patches" folder of the LSP.

The Patch Level 14 provides custom MMC/SD stack with SDIO support on both DM355 and DM644x devices. Detailed information on the Linux SDIO stack project can be obtained from the project's SourceForge page here. The custom MMC/SD stack provides improved performance and adds support for High Capacity SD cards. The Atheros AR6000 WLAN driver (reference only) has also been provided. Please note that custom MMC/SD stack is not a MontaVista product. The custom MMC/SD stack patches are not part of the default series file containing all other patches. The custom MMC/SD stack patches are part of a separate series file - series.sdiostack The Patch Level 14 also provides fixes for Video dislay issues and USB OTG issues.

Details on the LSP 1.20 patch set:

lsp_1_20_dm644x_pg_2_1_vid0_revert_field_inversion_fix_001 Patch for supporting VIDWIN0 on DM644x PG 2.1. A workaround to "Advisory 1.3.8, VPBE: OSD Field Signal is Inverted for All but Video Window 0" was included in the display driver of LSP 1.20 production release. The display driver disabled the VIDWIN0 and inverted the field signals for all other window planes to bypass the issue as described in the advisory. This patch detects the silicon version the software is running on, and reverts the workaround for PG 2.1 silicon. On PG 1.x silicon, the workaround will remain in place and VIDWIN0 will remain disabled.
