* armv7: add reset timeout to identify_nand_chipLadislav Michl2016-07-22-1/+1
| | | | | | | | | | identify_nand_chip hangs forever in loop when NAND is not present. As IGEPv2 comes either with NAND or OneNAND flash, add reset timeout to let function fail gracefully allowing caller to know NAND is not present. On NAND equipped board, reset succeeds on first read, so 1000 loops seems to be safe timeout. Signed-off-by: Ladislav Michl <ladis@linux-mips.org>
* omap-common: Common function to display die id, replacing omap3-specific versionPaul Kocialkowski2015-10-22-1/+0
| | | | | | | | | This introduces omap_die_id_display to display the full die id. There is no need to store it in an environment variable, that no boot script is using anyway. Signed-off-by: Paul Kocialkowski <contact@paulk.fr> Reviewed-by: Tom Rini <trini@konsulko.com>
* omap3: omap_die_id supportPaul Kocialkowski2015-10-22-1/+0
| | | | | | | | This replaces the previous get_dieid definition with omap_die_id, that matches the common omap_die_id definition. Signed-off-by: Paul Kocialkowski <contact@paulk.fr> Reviewed-by: Tom Rini <trini@konsulko.com>
* omap3: Definitions for SYS_BOOT-based fallback boot device selectionPaul Kocialkowski2015-07-27-1/+0
| | | | | | | This introduces code to read the value of the SYS_BOOT pins on the OMAP3, as well as the memory-preferred scheme for the interpretation of each value. Signed-off-by: Paul Kocialkowski <contact@paulk.fr>
* omap-common: Common boot code OMAP3 support and cleanupPaul Kocialkowski2015-07-27-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces OMAP3 support for the common omap boot code, as well as a major cleanup of the common omap boot code. First, the omap_boot_parameters structure becomes platform-specific, since its definition differs a bit across omap platforms. The offsets are removed as well since it is U-Boot's coding style to use structures for mapping such kind of data (in the sense that it is similar to registers). It is correct to assume that romcode structure encoding is the same as U-Boot, given the description of these structures in the TRMs. The original address provided by the bootrom is passed to the U-Boot binary instead of a duplicate of the structure stored in global data. This allows to have only the relevant (boot device and mode) information stored in global data. It is also expected that the address where the bootrom stores that information is not overridden by the U-Boot SPL or U-Boot. The save_omap_boot_params is expected to handle all special cases where the data provided by the bootrom cannot be used as-is, so that spl_boot_device and spl_boot_mode only return the data from global data. All of this is only relevant when the U-Boot SPL is used. In cases it is not, save_boot_params should fallback to its weak (or board-specific) definition. save_omap_boot_params should not be called in that context either.

* ARM: OMAP3: rx51: Enable workaround for ARM errata 454179, 430973, 621766Nishanth Menon2015-03-13-0/+1
| | | | | | | | | | | | RX51 has a secure logic which uses different parameters compared to traditional implementation. So, make the generic secure acr write over-ride-able by board file and refactor rx51 code to use this. While at it, enable the OMAP3 specific errata code for 454179, 430973, 621766.

* ARM: OMAP3: Get rid of omap3_gp_romcode_call and replace with omap_smc1Nishanth Menon2015-03-13-1/+0
| | | | | | | | | | | | omap_smc1 is now generic enough to remove duplicate omap3_gp_romcode_call logic that omap3 introduced. As part of this change, move to using the generic lowlevel_init.S for omap3 as well.
