* common: Discard the __u_boot_cmd sectionMarek Vasut2012-10-22-9/+0
| | | | | | | | | | | The command declaration now uses the new LG-array method to generate list of commands. Thus the __u_boot_cmd section is now superseded and redundant and therefore can be removed. Also, remove externed symbols associated with this section from include/command.h .

* common: Add .u_boot_list into all linker filesMarek Vasut2012-10-22-0/+15

* common: Add symbol handling for generic lists into MakefileMarek Vasut2012-10-22-18/+63
| | | | | | | | | | | | | | | | | | | | | | | This patch adds essential components for generation of the contents of the linker section that is used by the linker-generated array. All of the contents is held in a separate file, u-boot.lst, which is generated at runtime just before U-Boot is linked. The purpose of this code is to especially generate the appropriate boundary symbols around each subsection in the section carrying the linker-generated arrays. Obviously, the interim linker code for actual placement of the variables into the section is generated too. The generated file, u-boot.lst, is included into u-boot.lds via the linker INCLUDE directive in u-boot.lds . Adjustments are made in the Makefile and spl/Makefile so that the u-boot.lds and u-boot-spl.lds depend on their respective .lst files.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's use the more appropriate udelay for the nand_spl. While we can't make use of u-boot's full udelay we can atl east use a for loop that won't get optimized away .Since we have the bus clock we can use the timebase to calculate wall time. Looked at reusing the u-boot udelay functions but it pulls in a lot of code and would require quite a bit of work to keep us within the very small space constrains we currently have Signed-off-by: Matthew McClintock <msm@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

This comparison will properly shift the SVR and mask off the E bit This fixes the boot output to show the correct DDR bus width: 512 MiB (DDR3, 16-bit, CL=5, ECC off) instead of 512 MiB (DDR3, 32-bit, CL=5, ECC off) Signed-off-by: Matthew McClintock <msm@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

This allows us to get rid of CONFIG_SYS_NAND_ECCSTEPS and CONFIG_SYS_NAND_ECCTOTAL now, which would otherwise be likely to linger unreferenced after a conversion. It also eliminates a temporary error in the hawkboard_nand build, since the spl version of the patch removed ECCSTEPS/TOTAL from hawkboard.h, but the spl conversion is pending (and may be merged via a different tree).

* Fix regression in SMDK6400Simon Schwarz2011-12-06-3/+6
| | | | | | | | | | | | | | | | | | | s3c64xx.c implemented its own nand_read_byte, nand_write_buf and nand_read_buf functions. This provoked a regression when these functions were made public by patch 55f429bb39614a16b1bacc9a8bea9ac01a60bfc8. This deletes these duplicated functions from s3c64xx.c and adds the generic implementations in nand_base.c to the spl Makefile. It also adds -ffcuntion-sections and -gc-sections to the compilation flags of the SPL to avoid errors originating from unused functions in nand_base.c.

Note that using hardware ECC on IFC with small-page NAND (which is what comes on the p1010rdb reference board) means there will be insufficient OOB space for JFFS2, since IFC does not support 1-bit ECC. UBI should work, as it does not use OOB for anything but ECC. When hardware ECC is not enabled in CSOR, software ECC is now used.

P2020RDB-PC differs from the P102x RDB-PC with 64-bit DDR and 100Mhz SYSCLK. Key features on these boards include: * DDR3 * NOR flash * NAND flash (on RDB's only) * SPI flash (on RDB's only) * SDHC/MMC card slot * VSC7385 Ethernet switch (on P1020MBG, P1020RDB, & P1021RDB) * PCIE slot and mini-PCIE slots As these boards use soldered DDR chips not regular DIMMs, an on-board EEPROM is used to store SPD data. In case of absent or corrupted SPD, falling back to timing data embedded in the source code will be used. Raw timing data is extracted from DDR chip datasheet. Different speeds of DDR are supported with this approach. ODT option is forced to fit this set of boards, again because they don't have regular DIMMs. CONFIG_SYS_EEPROM_PAGE_WRITE_DELAY_MS is defined as 5ms to meet specification for writing timing. VSC firmware Address is defined by default in config file for eTSEC1. SD width is based off DIP switch. DIP switch is detected on the board by reading i2c bus and setting the appropriate mux values. Some boards have QE module in the silicon (P1021 and P1025). QE and eLBC have pins multiplexing. QE function needs to be disabled to access Nor Flash and CPLD. QE-UEC and QE-UART can be enabled for linux kernel by setting "qe" in hwconfig. In addition, QE-UEC and QE-TDM also have pins multiplexing, to enable QE-TDM for linux kernel, set "qe;tdm" in hwconfig. Syntax is as below 'setenv hwconfig qe' to enable QE UEC/UART and disable Nor-Flash/CPLD. 'setenv hwconfig 'qe;tdm'' to enalbe QE TDM and disable Nor-Flash/CPLD.

* NAND: Add 16bit NAND support for the NDFCAlex Waterman2011-07-01-3/+8
| | | | | | | | | | | | | | | | | | | This patch adds support for 16 bit NAND devices attached to the NDFC on ppc4xx processors. Two config entries were added: CONFIG_SYS_NDFC_16 - Setting this tells the NDFC that a 16 bit device is attached. CONFIG_SYS_NDFC_EBC0_CFG - This is for the External Bus Controller configuration register. Also, a new ndfc_read_byte() function was added which does not first convert the data to little endian. The NAND SPL was also modified to do 16bit bad block testing when a 16 bit chip is being used. Signed-off-by: Alex Waterman <awaterman@dawning.com> Signed-off-by: Scott Wood <scottwood@freescale.com>

* nand_spl: nand_boot.c: Remove CONFIG_SYS_NAND_READ_DELAYStefan Roese2011-05-13-18/+6
| | | | | | | | | | | | | | | | | | | | | | | | There are multiple reasons why this define should be removed: First it saves some space and therefore fixes a problem we have on the canyonlands_nand and glacier_nand targets right now. Second, the define was hackish and would most likely not work on all board using nand_boot.c. Boards not providing a real dev_ready() function should implement a board specific function instead. I checked and it seems, that all boards using nand_boot.c right now already implement a board specific dev_ready() function. So this patch should not break any boards and will result in smaller NAND_SPL images.

| | | | | | | | | | As exception among the i.MX processors, the i.MX31 has headers without general names (mx31-regs.h, mx31.h instead of imx-regs.h and clock.h).
