2009-10-13TI DaVinci: DM646x: Initial Support for DM646x SOCSandeep Paulraj
DM646x is an SOC from TI which has both an ARM and a DSP. There are multiple variants of the SOC mainly dealing with different core speeds. This patch adds the initial framework for the DM646x SOC. Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
2009-10-13OMAP3 Move cache routine to cache.STom Rix
v7_flush_dcache_all, because it depends on omap ROM code is not generic. Rename the function to 'invalidate_dcache' and move it to the omap cpu directory. Collect the other omap cache routines l2_cache_enable and l2_cache_disable with invalide_dcache into cache.S. This means removing the old cache.c file that contained l2_cache_enable and l2_cache_disable. The conversion from cache.c to cache.S was done most through disassembling the uboot binary. The only significant change was to change the comparision for the return of get_cpu_rev from cmp r0, #0 beq earlier_than_label Which was lost information to cmp r0, #CPU_3XX_ES20 blt earlier_than_label The paths through the enable routine were verified by adding an infinite loop and seeing the hang. Then removing the infinite loop and seeing it continue. The disable routine is similar enough that it was not tested with this method. Run tested by cold booting from nand on beagle and zoom1. Compile tested on MAKEALL arm. Signed-off-by: Tom Rix <Tom.Rix@windriver.com>
2009-10-03arm/microblaze/nios/nios2/sh: Remove relocation fixupsPeter Tyser
These architectures don't need relocation fixups, so reduce their codesize a bit by defining CONFIG_RELOC_FIXUP_WORKS. Also remove the reloc_off field from their global data structures as it is no longer needed. Note that the location of the standalone application jump table pointer in the global data structure is affected by this change, breaking execution of standalone applications compiled for previous versions of U-Boot. We will therefore increment XF_VERSION in the next commit, which also touches this area. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Wolfgang Denk <wd@denx.de>

2009-09-01arm: Kirkwood: add SYSRSTn Duration Counter SupportPrafulla Wadaskar
This feature can be used to trigger special command "sysrstcmd" using reset key long press event and environment variable "sysrstdelay" is set (useful for reset to factory or manufacturing mode execution) Kirkwood SoC implements a hardware-based SYSRSTn duration counter. When SYSRSTn is asserted low, a SYSRSTn duration counter is running. The counter value is stored in the SYSRSTn Length Counter Register The counter is based on the 25-MHz reference clock (40ns) It is a 29-bit counter, yielding a maximum counting duration of 2^29/25 MHz (21.4 seconds). When the counter reach its maximum value, it remains at this value until counter reset is triggered by setting bit 31 of KW_REG_SYSRST_CNT Implementation: Upon long reset assertion (> ${sysrstdelay} in secs) sysrstcmd will be executed if pre-defined in environment variables. This feature will be disabled if "sysrstdelay" variable is unset. for-ex. setenv sysrst_cmd "echo starting factory reset; nand erase 0xa0000 0x20000; echo finish ed sysrst command;" will erase particular nand sector if triggered by this event Signed-off-by: Prafulla Wadaskar <prafulla@marvell.com>

2009-08-17Monahans: avoid floating point calculationsWolfgang Denk
Current code for the Monahans CPU defined OSCR_CLK_FREQ as 3.250 (MHz) which caused floating point operations to be used.

The prescalar that converts the function clock to the sampling clock is hardcoded to 0. The reference manual recommends 7 if the function clock is 96MHz. Instead of just changing the hardcoded values, the prescalar is calculated from the value I2C_IP_CLK. The i2c #defines are in kHz. The speed passed into the i2c init routine is in Hz. To be consistent, change the defines to be in Hz. The timing calculations are based on what is done in the linux 2.6.30 kernel in drivers/i2c/buses/i2c_omap.c as apposed to what is done in TRM. The major variables in the timing caculations are specified as #defines that can be overriden as required. The variables and their defaults are I2C_IP_CLK SYSTEM_CLOCK_96 I2C_INTERNAL_SAMPLING_CLK 19200000 I2C_FASTSPEED_SCLL_TRIM 6 I2C_FASTSPEED_SCLH_TRIM 6 I2C_HIGHSPEED_PHASE_ONE_SCLL_TRIM I2C_FASTSPEED_SCLL_TRIM I2C_HIGHSPEED_PHASE_ONE_SCLH_TRIM I2C_FASTSPEED_SCLH_TRIM I2C_HIGHSPEED_PHASE_TWO_SCLL_TRIM I2C_FASTSPEED_SCLL_TRIM I2C_HIGHSPEED_PHASE_TWO_SCLH I2C_FASTSPEED_SCLH_TRIM This was runtime verified on Zoom1, Zoom2, Beagle and Overo. The 400kHz and 3.4M cases were verifed on test Zoom1, Zoom2, Beagle and Overo configurations. Testing for omap2 will be done in a second step as Nishanth and Jean-Christophe commented.

2009-07-07davinci_nand chipselect/init cleanupDavid Brownell
Update chipselect handling in davinci_nand.c so that it can handle 2 GByte chips the same way Linux does: as one device, even though it has two halves with independent chip selects. For such chips the "nand info" command reports: Device 0: 2x nand0, sector size 128 KiB Switch to use the default chipselect function unless the board really needs its own. The logic for the Sonata board moves out of the driver into board-specific code. (Which doesn't affect current build breakage if its NAND support is enabled...)

2009-07-07davinci_nand: cleanup II (CONFIG_SYS_DAVINCI_BROKEN_ECC)David Brownell
Remove CONFIG_SYS_DAVINCI_BROKEN_ECC option. It's not just nasty; it's also unused by any current boards, and doesn't even match the main U-Boot distributions from TI (which use soft ECC, or 4-bit ECC on newer chips that support it). DaVinci GIT kernels since 2.6.24, and mainline Linux since 2.6.30, match non-BROKEN code paths for 1-bit HW ECC. The BROKEN code paths do seem to partially match what MontaVista/TI kernels (4.0/2.6.10, and 5.0/2.6.18) do ... but only for small pages. Large page support is really broken (and it's unclear just what software it was trying to match!), and the ECC layout was making three more bytes available for use by filesystem (or whatever) code. Since this option itself seems broken, remove it. Add a comment about the MV/TI compat issue, and the most straightforward way to address it (should someone really need to solve it).
