* ARM: mxs: Add OCOTP driverMarek Vasut2014-03-31-0/+5
| | | | | | | | | | | | Add yet another OCOTP driver for this i.MX family. This time, it's a driver for the OCOTP variant found in the i.MX23 and i.MX28. This version of OCOTP is too different from the i.MX6 one that I could not use the mxc_ocotp.c driver without making it into a big pile of #ifdef . This driver implements the regular fuse command interface, but due to the IP blocks' limitation, we support only READ and PROG functions.

* arm: mxs: Adjust the load address of U-Boot and SPL for HABMarek Vasut2014-03-31-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | When using HAB, there are additional special requirements on the placement of U-Boot and the U-Boot SPL in memory. To fullfill these, this patch moves the U-Boot binary a little further from the begining of the DRAM, so the HAB CST and IVT can be placed in front of the U-Boot binary. This is necessary, since both the U-Boot and the IVT must be contained in single CST signature. To make things worse, the IVT must be concatenated with one more entry at it's end, that is the length of the entire CST signature, IVT and U-Boot binary in memory. By placing the blocks in this order -- CST, IVT, U-Boot, we can easily align them all and then produce the length field as needed. As for the SPL, on i.MX23/i.MX28, the SPL size is limited to 32 KiB, thus we place the IVT at 0x8000 offset, CST right past IVT and claim the size is correct. The HAB library accepts this setup. Finally, to make sure the vectoring in SPL still works even after moving the SPL from 0x0 to 0x1000, we add a small function which copies the vectoring code and tables to 0x0. This is fine, since the vectoring code is position independent. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Stefano Babic <sbabic@denx.de>
* configs: Delete obsolete macro, CONFIG_SYS_GBL_DATA_SIZEMasahiro Yamada2014-02-19-1/+0
| | | | | | | | | | | CONFIG_SYS_GBL_DATA_SIZE is not used any more. The size of struct "global_data" is automatically calculated by asm-offsets. (See lib/asm-offsets.c) GENERATED_GBL_DATA_SIZE should be used instead of CONFIG_SYS_GBL_DATA_SIZE. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

* config: Add a default CONFIG_SYS_PROMPTRob Herring2013-11-04-1/+0
| | | | | | | | | | The definitions for CONFIG_SYS_PROMPT are varied with little reason other than to display the board name. Over half the definitions are "==> ", so make this the default. The rest of the boards remain unchanged to avoid breaking any external scripts expecting a certain prompt.

* ARM: mxs: Consolidate configuration optionsMarek Vasut2013-07-24-0/+191
Pull all the duplicate configuration options into configs/mxs.h from the board configuration files. This reduces the files greatly and makes them somewhat more readable. Besides, we do no longer have such a horrible duplication of code. Note that the mx23evk grew in size slightly. This is due to the CONFIG_SYS_CBSIZE now being set to 1024 as it is on the rest of MXS systems. This patch also fixes the OCRAM size for i.MX23. The i.MX23 has only 32kB of OCRAM, while i.MX28 has 128kB of OCRAM. I verified the configuration didn't change for each of the boards, but I didn't boot-test it on the boards I do not have. I configured U-Boot for each board using the "make ... <board>_config" command and then ran "cpp -I include -dM include/config.h" , which dumped all the configuration options. I did this both before and after this patch and finally compared the results for each MXS board. Actually, the results do differ slightly, since the configs/mxs.h file now properly includes the correct iomux-mx23.h or iomux-mx28.h , so while comparing, I had to ignore these new defines. These have no impact on U-Boot configuration though.
