* mtd: nand: denali: max_banks calculation changed in revision 5.1Graham Moore2016-04-011-1/+10
| | | | | | | | | | | | | | Read Denali hardware revision number and use it to calculate max_banks, The encoding of max_banks changed in Denali revision 5.1.

* mtd: denali: fix warning when compiled for 64bit systemMasahiro Yamada2016-03-241-3/+3
| | | | | | | | | | The 64-bit compiler (ex. aarch64) emits "warning: cast from pointer to integer of different size". Make it work with 64bit DMA address while I am here. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Tom Rini <trini@konsulko.com>
* nand: Sync with Linux v4.1Scott Wood2015-08-251-94/+115
| | | | | | | | | | | Update the NAND code to match Linux v4.1. The previous sync was from Linux v3.15 in commit 4e67c57125290b25. CONFIG_SYS_NAND_RESET_CNT is removed, as the upstream Linux code now has its own timeout. Plus, CONFIG_SYS_NAND_RESET_CNT was undocumented and not selected by any board.

* mtd: denali: set some registers after nand_scan_ident()Masahiro Yamada2014-11-261-0/+11
| | | | | | | | | | | | | | | | | Some but not all of implementations of the Denali NAND controller have hardware circuits to detect the device parameters such as page_size, erase_size, etc. Even on those SoCs with such hardware supported, the hardware is known to detect wrong parameters for some nasty (almost buggy) NAND devices. The device parameters detected during nand_scan_ident() are more trustworthy. This commit sets some hardware registers to mtd->pagesize, mtd->oobsize, etc. in the code between nand_scan_ident() and nand_scan_tail().

* mtd: denali: use CONFIG_SYS_NAND_SELF_INITMasahiro Yamada2014-11-261-37/+84
| | | | | | | | | | | | | | | | Some variants of the Denali NAND controller need some registers set up based on the device information that has been detected during nand_scan_ident(). CONFIG_SYS_NAND_SELF_INIT has to be defined to insert code between nand_scan_ident() and nand_scan_tail(). It is also helpful to reduce the difference between this driver and its Linux counterpart because this driver was ported from Linux. Moreover, doc/README.nand recommends to use CONFIG_SYS_NAND_SELF_INIT.

* mtd: denali: support NAND_CMD_RNDOUT commandMasahiro Yamada2014-10-091-0/+7
| | | | | | | | | | | | The function nand_flash_detect_ext_param_page() requires NAND_CMD_RNDOUT command supported. It is necessary to detect some types of ONFi-compliant devices. Without it, the error message "unsupported command received 0x5" is shown. Let's support this command on the Denali NAND controller driver.

* mtd: denali: fix NAND_CMD_PARAM commandMasahiro Yamada2014-10-091-2/+3
| | | | | | | | | | | | | | | NAND_CMD_PARAM (0xEC) command is not working on the Denali NAND controller driver. Unlike NAND_CMD_READID (0x90), when the NAND_CMD_PARAM command is followed by an address cycle, the target device goes busy. (R/B# is deasserted) Wait until the parameter data are ready. In addition, unnecessary clear_interrupts() should be removed. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Chin Liang See <clsee@altera.com>
* nand/denali: Adding Denali NAND driver supportChin Liang See2014-09-251-0/+1205
To add the Denali NAND driver support into U-Boot. This driver is leveraged from Linux with commit ID fdbad98dff8007f2b8bee6698b5d25ebba0471c9. For Denali controller 64 variance, you need to declare macro CONFIG_SYS_NAND_DENALI_64BIT.
