This series of patches bring the legacy NXP LPC32xx BSP drivers SLC NAND (hardware ECC), DMA & USB into the latest u-boot.
Refer to each individual patches for details on the change done to integrate the driver into the latest u-boot.
The legacy BSP patch (u-boot-2009.03_lpc32x0-v1.07.patch.tar.bz2) was downloaded from the LPCLinux Web site.
The patch adding the LPC32xx MAC and SMSC RMII phy support should be applied first: - http://patchwork.ozlabs.org/patch/489100/ - http://patchwork.ozlabs.org/patch/489190/ - http://patchwork.ozlabs.org/patch/491419/ - http://patchwork.ozlabs.org/patch/491420/
The SLC NAND patch should be applied after: - https://patchwork.ozlabs.org/patch/497308/
The patch modifying the I2C to use the HCLK get API function should be applied after the SLC NAND patch: - https://patchwork.ozlabs.org/patch/500511/
The NAND driver was only tested for large page NAND.
Potential test opportunity for small page NAND: - Since the equivalent of the legacy NXP BSP drivers are available (NAND SLC / DMA / Ethernet / USB), it will be nice if somebody using the PHY3250 development board can test small pafe NAND. - The remaining porting work to the latest u-boot include the migration of the board & configuration files.
Changes from v1 to v2: * Moved the DMA patch as the first patch of the series and the NAND SLC patch as thesecond one. * As per discussion on mailing list with Vladimir, incorporate NAND SLC hardware ECC support into the following NAND SLC patch: https://patchwork.ozlabs.org/patch/497308/ * As per discussion on mailing list with Vladimir & Albert, add conditional compile option to build the original NAND SLC code using software ECC for SPL build. * Moved ECC layout for small page NAND in a separate patch. * Addressed Marek's comments on LPC32xx USB driver: - use "get_timer()" to handle timeout. - Split USB and I2C driver. * Updated LPC32xx I2C driver to support the I2C that is part of the USB module. * Removed ISP1301 USB transceiver I2C registers definition that are not used. * For the USB driver, use "cpu" initialization & stop functions API instead of the "board" API.
Note: I am sending the patches using slemieux.tyco@gmail.com, until I can submit patch using my regular e-mail slemieux@tycoint.com.
