* ARM: OMAP: bbu: Add an all-in-one NAND update handlerSascha Hauer2019-08-282-0/+152
| | | | | | | | | | This adds a NAND update handler which automatically detects on the filetype which stage shall be updated. It takes a single partition for both the xload images and the barebox images. It uses a fixed layout on this partition, so there's no need to configure anything on the board side.

* mtd: nand: gpmc: Add BCH16 supportSascha Hauer2019-08-281-0/+1
| | | | | | | | | | | | | | | | This adds support for BCH16 ECC encoding. The support is mostly taken from Linux-5.3-rc6. One major change is the different wrap mode used. The Kernel uses wrapmode 1, which means "pass all data through the BCH engine". Still the Kernel has to skip the OOB marker which is done by reading all user data, then use NAND_CMD_RNDOUT to position right behind the OOB marker and then read the ECC data. Instead of doing this we use wrap mode 4 which allows us to bypass the OOB marker from the BCH engine automatically. This explains bch_wrapmode = 1, eccsize0 = 0, eccsize1 = 52 vs. bch_wrapmode = 4, eccsize0 = 4, eccsize1 = 52 Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: omap: am35xx_emif4: Fix bit pollingSascha Hauer2019-08-281-1/+1
| | | | | | | | | ((x & (1 << 10)) == 0x1) can never be true as the compiler mourns about. Fix this to actually do what the comment says: Wait till bit 10 is cleared. Looking at the corresponding U-Boot code also suggests that this is the right thing to do. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | ARM: omap3: Add support for reset reason detectionOleg Karfich2018-12-201-0/+49
| | | | | | | | | | | | | | | | | | | | Due to the Errata i520, the reset code in the linux kernel aswell in barebox triggers a cpu reset by setting the bit RST_DPLL3 in the PRM_RSTCTRL register. This induces a global cold reset on the chip. So we will always detect a POR as reset source when a reboot of the chip is triggerd. Other states like WDG, JTAG were tested successfully.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two differences between file_write_flash() and write_image() (which is removed in this patch): - file_write_flash() uses write_full() vs. write() in write_image() - file_write_flash() doesn't erase the whole device but only the needed space So the new code should be more robust and maybe even faster.

| * net: dhcp: reworkSascha Hauer2017-12-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DHCP code is a mess. It is not clear which options are sent to the server and which options are returned from the server. Also environment variables are read from and written to all over the place. This patch cleans this up. There now is struct dhcp_req_param which is used for options sent to the server and struct dhcp_result which contains the values sent from the server. The values from the server are written to the barebox variables in a single place. Also it's now possible to call the dhcp code without modifying barebox variables at all, storing the result only in the dhcp result struct. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* arm: am33xx: Initialize EMIF REG_PR_OLD_COUNTDaniel Schultz2017-01-302-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is based on a patch from the U-Boot and fixes two errors with the LCDC. Original commit message from Jyri Sarha [1]: "Initialize EMIF OCP_CONFIG registers REG_COS_COUNT_1, REG_COS_COUNT_2, and REG_PR_OLD_COUNT field for Beaglebone-Black and am335x-evm. With the default values LCDC suffers from DMA FIFO underflows and frame synchronization lost errors. The initialization values are the highest that work flawlessly when heavy memory load is generated by CPU. 32bpp colors were used in the test. On BBB the video mode used 110MHz pixel clock. The mode supported by the panel of am335x-evm uses 30MHz pixel clock." The register values are generated by testing, because there is no formula to calculate them. Also from Jyri Sarha [1]: "In practice the only rule to find an optimal value is to find as high as possible REG_PR_OLD_COUNT value that does not produce LCDC FIFO underflows under worst case scenario. The worst case happens when the highest pixel clock videomode with maximum bpp is used while memory subsystem is stressed by endless stream of writes hitting the same memory memory bank (can be the same address)." It only contains the BeagleBone Black and the Phytec SoM, because I don't have other boards.
