2012-02-12Changes to move hawkboard to the new spl infrastructureSughosh Ganu
This patch moves hawkboard to the new spl infrastructure from the older nand_spl one. Removed the hawkboard_nand_config build option -- The spl code now gets compiled with hawkboard_config, after building the main u-boot image, using the CONFIG_SPL_TEXT_BASE. Modified the README.hawkboard to reflect the same.

2011-12-06arm, hawkboard: Use the pinmux configurations defined in the arch treeChristian Riesch
The boards in board/davinci/da8xxevm/ define pinmux_config[] vectors that contain pinmux configurations for emac, uarts, memory controllers... In an earlier patch such pinmux configurations were added to the arch tree. This patch makes the hawkboard use these definitions instead of defining its own.

2011-12-06Fix regression in SMDK6400Simon Schwarz
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.

2011-09-29powerpc/85xx: Add support for new P102x/P2020 RDB style boardsLi Yang
The following boards share a common design but with minor variations between them: P1020MSBG-PC P1020RDB-PC P1020UTM-PC P1021RDB-PC P1024RDB P1025RDB P2020RDB-PC The P1020RDB-PC shares its roots in the existing P1020RDB board design, however uses DDR3 instead of DDR2. 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.

2010-12-16powerpc/nand spl: link libgccScott Wood
Recent GCC (4.4+) performs out-of-line epilogues in some cases, when optimizing for size. It causes a link error for _restgpr_30_x (and similar) if libgcc is not linked. It actually increases size with very small binaries, due to the fixed size of the out-of-line code, and not having any functions that actually need to restore more than 2 or 3 registers. But I don't see a way to turn it off, other than asking GCC to optimize for speed -- which may also increase size for some boards.

2010-11-30Add board support for hawkboardSughosh Ganu
The patch adds basic board support for TI's OMAP-L138 based Hawkboard. This board is pretty similar to the da850 EVM. Support for nand and network access is added in this version. The following bootup procedure is used. At reset, the Rom Boot Loader(RBL), initialises the ddr and the nand controllers and copies the second stage bootloader(nand_spl) to RAM. The secondary bootloader then copies u-boot from a predefined location in the nand flash to the RAM, and passes control to the u-boot image. Three config options are supported * hawkboard_config - Used to create the u-boot.bin. Tftp the u-boot.bin image to the RAM from u-boot, and flash to the nand flash at address 0xe0000. * hawkboard_nand_config - Used to generate the secondary bootloader(nand_spl) image. This creates an elf file u-boot-spl under nand_spl/. Create an AIS signed image using this file, and flash it to the nand flash at address 0x20000. The ais file should fit in one block. * hawkboard_uart_config - This is same as the first image, but with the TEXT_BASE as expected by the RBL(0xc1080000).

Apply the same fix for 83xx as was done for 85xx in commit 96196a1f7546904563994d2d041804a816d7c139. Without this, NAND SPLs are built with the text base intended for the main image, resulting in a broken, very large u-boot-nand.bin. The block of defines for NAND boot is moved closer to where CONFIG_SYS_TEXT_BASE is defined. We can't directly use CONFIG_SYS_NAND_U_BOOT_DST in the definition of CONFIG_SYS_TEXT_BASE because autoconf.mk will include the literal text "CONFIG_SYS_NAND_U_BOOT_DST", but at least keep them close and point out that they're supposed to be the same.

Currently, 83xx, 86xx, and 85xx have a lot of duplicated code dedicated to defining and manipulating the LBC registers. Merge this into a single spot. To do this, we have to decide on a common name for the data structure that holds the lbc registers - it will now be known as fsl_lbc_t, and we adopt a common name for the immap layouts that include the lbc - this was previously known as either im_lbc or lbus; use the former. In addition, create accessors for the BR/OR regs that use in/out_be32 and use those instead of the mismash of access methods currently in play.

2010-04-13Replace "#include <asm-$ARCH/$FILE>" with "#include <asm/$FILE>"Peter Tyser
The appropriate include/asm-$ARCH directory should already by symlinked to include/asm so using the whole "asm-$ARCH" path is unnecessary. This change should also allow us to move the include/asm-$ARCH directories into their appropriate lib/$ARCH/ directories. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2010-04-13Move lib_$ARCH directories to arch/$ARCH/libPeter Tyser
Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk This change is intended to clean up the top-level directory structure and more closely mimic Linux's directory organization. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2010-04-13Create CPUDIR variablePeter Tyser
The CPUDIR variable points to the location of a target's CPU directory. Currently, it is set to cpu/$CPU. However, using $CPUDIR will allow for more flexibility in the future. It lays the groundwork for reorganizing U-Boot's directory structure to support a layout such as: arch/$ARCH/cpu/$CPU/* (architecture with multiple CPU types) arch/$ARCH/cpu/* (architecture with one CPU type) Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
