2012-07-07ARM: OMAP3+: Detect reset typeLokesh Vutla
Certain modules are not affected by means of a warm reset and need not be configured again. Adding an API to detect the reset reason warm/cold. This will be used to skip the module configurations that are retained across a warm reset. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Signed-off-by: R Sricharan <r.sricharan@ti.com>
2012-05-25omap3_dss: cosmetic changesJeroen Hofstee

2012-05-25omap3_dss: add optional framebufferJeroen Hofstee
The beagle board uses the background color to show an orange screen during startup. This patch adds the ability to add a frame buffer, with the intention not to break the beagle board use case (I don't have one). videomodes.c is not used.

2012-05-15OMAP3+: reset: Create a common reset layer.SRICHARAN R
The reset.S has the function to do a warm reset on OMAP based socs. Moving this to a reset.c file so that this acts a common layer to add any reset related functionality for the future. Signed-off-by: R Sricharan <r.sricharan@ti.com>
2012-05-15ARM:OMAP+:MMC: Add parameters to MMC initJonathan Solnit
Add parameters to the OMAP MMC initialization function so the board can mask host capabilities and set the maximum clock frequency. While the OMAP supports a certain set of MMC host capabilities, individual boards may be more restricted and the OMAP may need to be configured to match the board. The PRG_SDMMC1_SPEEDCTRL bit in the OMAP3 is an example. Signed-off-by: Jonathan Solnit <jsolnit@gmail.com>
2012-02-15omap_hsmmc: Wait for CMDI to be clearTom Rini
Before we can send a command we need both the DATI (command inhibit on mmc_dat line) bit and CMDI (command inhibit on mmc_cmd line) are clear. The previous behavior of only checking on DATI was insufficient on some cards and incorrect behavior in any case. This makes the code check for both bits being clear and makes the error print more clear as to what happened. DATI_CMDDIS is removed as it was unused elsewhere in the code and stood for 'DATI is set, cmds are disabled still'. Fix originally spotted by Peter Bigot. Tested-by: Peter A.

All usb layers are not cache aligned, till then keep cache off for usb ops as ehci will use internally dma for all usb ops. * Add a generic common header ehci-omap.h having common ip block data and reg shifts. * Rename and modify ehci-omap3 to ehci.h retain only conflicting sysc reg shifts remove others and move to common header file. * pass the board data for beagle/panda accordinly to use ehci ports.

This introduces 200MHz Micron parts timing information based on x-loader to <asm/arch-omap3/mem.h> and Numonyx MCFG calculation. The memory init logic is also based on what x-loader does in these cases. Note that while previously u-boot would be flashed in with SW ECC in this case it now must be flashed with HW ECC.

2011-12-06OMAP3 SPL: Add identify_nand_chip functionTom Rini
A number of boards are populated with a PoP chip for both DDR and NAND memory. Other boards may simply use this as an easy way to identify board revs. So we provide a function that can be called early to reset the NAND chip and return the result of NAND_CMD_READID. All of this code is put into spl_id_nand.c and controlled via CONFIG_SPL_OMAP3_ID_NAND. Signed-off-by: Tom Rini <trini@ti.com>

AM/DM37x is another OMAP3 variant, where the GFX clock has been boosted to 192MHz/200MHz. So fix the GFX_DIV value for this change. HW Errata: Due to dependency of TV out clock of 54MHz, it is not possible to configure GFX to 192MHz. So as per HW errats, the recommended GFX clock is 200MHz (=CORE_CLK/2).
