* ARM: zynq: Remove zc70x targetMichal Simek2015-11-04-9/+1
| | | | | | | | Remove zc70x target which was one setting for zc702 and zc706. Currently zc702 and zc706 are separated. Signed-off-by: Michal Simek <michal.simek@xilinx.com> Reviewed-by: Joe Hershberger <joe.hershberger@ni.com>
* dm: arm: zynq: Enable device tree control in SPLSimon Glass2015-11-04-1/+9
| | | | | | | | Move to using device tree control in SPL so that we can use the same driver code in both SPL and U-Boot proper. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* arm: zynq: Support the debug UARTSimon Glass2015-11-04-0/+6
| | | | | | | | Add support for the debug UART to assist with early debugging. Enable it for Zybo as an example. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* arm: zynq: Drop unnecessary code in SPL board_init_f()Simon Glass2015-11-04-5/+1
| | | | | | | | | | Move to the new way of starting up SPL. Clearing of BSS and calling board_init_r() is now handled by crt0.S. Also tidy up the header include order. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* zynq: Move SPL console init out of board_init_f()Simon Glass2015-10-24-1/+1
| | | | | | | | | | | | | | We should not init the console this early since it precludes using driver model for the UART, since it is not set up at the start of board_init_f(). See the README for more information. The debug UART does not have this restriction. If we want to do early init with the console on it can be done in spl_board_init(). Move the preloader_console_init() call from board_init_f() to board_init_r().

* ARM: zynq: drop "optional" from board select in favor of ZC702Masahiro Yamada2015-08-19-1/+1
| | | | | | | | | | | | One disadvantage of commit a26cd04920dc (arch: Make board selection choices optional) is that Kconfig could create such an insane .config file that no board is selected. Rip off the "optional" again in favor of ZC702 as the default target. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* zynq: Rename struct clk_ops to zynq_clk_opsSimon Glass2015-07-21-3/+3
| | | | | | | Since we want clk_ops to be used in U-Boot as a whole, rename the Zynq version until it can be converted to driver model. Signed-off-by: Simon Glass <sjg@chromium.org>
* ARM: zynq: add default ps7_init_gpl.c/h for Zed, MicroZed, ZC70xMasahiro Yamada2015-05-25-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to licensing issues, the files ps7_init.c/h are not able to be distributed with U-Boot source code. Recent Xilinx tools also provide the GPL variants (ps7_init_gpl.c/h), compatible with U-Boot license. Prior to this commit, we had to copy ps7_init files into board/xilinx/zynq/ before the compile. To be more user-friendly, let's include ps7_init_gpl.c/h for Zedboard, MicroZed, ZC702, ZC706. These init code have been taken from the hwplatform_templates directory of Xilinx SDK 2014.4. You can still use customized ps7_init_gpl.c/h by enabling CONFIG_ZYNQ_CUSTOM_INIT. The recommended directory for storing them is now board/xilinx/zynq/custom_hw_platform, but board/xilinx/zynq is still supported for backward compatibility. The latter emits a warning message to prompt users to gradually switch to the new directory.

* ARM: zynq: add separate configuration for ZC702 and ZC706Masahiro Yamada2015-05-25-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | Prior to this commit, ZC702 and ZC706 shared the same configuration and were built as follows: ZC702: make zynq_zc70x_defconfig && make ZC706: make zynq_zc70x_defconfig && make DEVICE_TREE=zynq-zc706 This commit introduces separate configuration for them, which makes the next commit much easier. Going forward, the recommended build commands are: ZC702: make zynq_zc702_defconfig && make ZC706: make zynq_zc706_defconfig && make Although the old work flow is still supported, CONFIG_TARGET_ZC70X has been marked as deprecated. If used, the warning message is shown to prompt users to switch to the new scheme.

* zynq: Use system timer implementation instead of ourMichal Simek2015-05-25-83/+1
| | | | | | | Don't use error-prone arch timer code and instead use system timer implementation to simplify our code. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* arch: Make board selection choices optionalJoe Hershberger2015-05-12-0/+1
| | | | | | | | | | | | By making the board selections optional, every defconfig will include the board selection when running savedefconfig so if a new board is added to the top of the list of choices the former top's defconfig will still be correct.
