* arm: socfpga: set the mpuclk divider in the Altera group registerDinh Nguyen2017-02-08-0/+3
| | | | | | | | | | | | | The mpuclk register in the Altera group of the clock manager divides the mpu_clk that is generated from the C0 output of the main pll. Without this patch, the default value of the register is 1, so the mpuclk will always get divided by 2 if the correct value is not set. For example, on the Arria5 socdk board, the MPU clock is only 525 MHz, and it should be 1.05 GHz. Signed-off-by: Dinh Nguyen <dinguyen@kernel.org>
* ARM: socfpga: Add boot0 hook to prevent SPL corruptionMarek Vasut2016-12-06-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Valid Altera SoCFPGA preloader image must contain special data at offsets 0x40, 0x44, 0x48 and valid instructions at address 0x4c or 0x50. These addresses are by default used by U-Boot's vector table and a piece of reset handler, thus a valid preloader corrupts those addresses slightly. While this works most of the time, this can and does prevent the board from rebooting sometimes and triggering this issue may even depend on compiler. The problem is that when SoCFPGA performs warm reset, it checks the addresses 0x40..0x4b in SRAM for a valid preloader signature and header checksum. If those are found, it jumps to address 0x4c or 0x50 (this is unclear). These addresses are populated by the first few instructions of arch/arm/cpu/armv7/start.S: ffff0040 <data_abort>: ffff0040: ebfffffe bl ffff0040 <data_abort> ffff0044 <reset>: ffff0044: ea000012 b ffff0094 <save_boot_params> ffff0048 <save_boot_params_ret>: ffff0048: e10f0000 mrs r0, CPSR ffff004c: e200101f and r1, r0, #31 ffff0050: e331001a teq r1, #26 Without this patch, the CPU will enter the code at 0xffff004c or 0xffff0050 , at which point the value of r0 and r1 registers is undefined. Moreover, jumping directly to the preloader entry point at address 0xffff0000 will also fail, because address 0xffff004. is invalid and contains the preloader magic. Add BOOT0 hook which reserves the area at offset 0x40..0x5f and populates offset 0x50 with jump to the entry point. This way, the preloader signature is stored in reserved space and can not corrupt the SPL code.

* arm: socfpga: Make the pinmux table const u8Marek Vasut2015-08-23-2/+1
| | | | | | | | | | | Now that we're actually converting the QTS-generated header files, we can even adjust their data types. A good candidate for this is the pinmux table, where each entry can have value in the range of 0..3, but each element is declared as unsigned long. By changing the type to u8, we can save over 600 Bytes from the SPL, so do it. This patch also constifies the array. Signed-off-by: Marek Vasut <marex@denx.de>

* arm: socfpga: system: Clean up pinmux_config.cMarek Vasut2015-08-08-3/+2
| | | | | | | | | | | | | | | Implement new accessor, sysmgr_get_pinmux_table(), used to obtain pinmux table and it's size from the QTS-generated pinmux_config.c. The target here is again to get rid of poluting global namespace by including the pinmux_config.h into it. Furthermore, the pinmux_config.h declares some CONFIG_HPS_* macros, which are explicitly useless to us in U-Boot. Instead, U-Boot does use DT to detect exactly these configuration options. This patch makes sure that while this QTS-generated file can stay in the tree, these obscure macros do not ooze into the namespace anymore. Signed-off-by: Marek Vasut <marex@denx.de>

* arm: socfpga: scan: Zap iocsr_scan_chain*_table()Marek Vasut2015-08-08-9/+3
| | | | | | | | | | | | | | | | | | | | | | Introduce accessor iocsr_get_config_table() for retrieving IOCSR config tables. This patch is again trimming down the namespace polution. The IOCSR config tables are used only by scan manager, they are generated by qts and are board specific. Before this patch, the approach to use these tables in scan manager was to define an extern variable to silence the compiler and compile board-specific iocsr_config.c into U-Boot which defined those extern variables. Furthermore, since these are tables and the scan manager needs to know the size of those tables, iocsr_config.h is included build-wide. This patch wraps all this into a single accessor which takes the scan chain ID and returns pointer to the table and it's size. All this is wrapped in wrap_iocsr_config.c board-specific file. The file includes the iocsr_config.c (!) to access the original tables and transitively iocsr_config.h . It is thus no longer necessary to include iocsr_config.h build-wide and the namespace polution is trimmed some more. Signed-off-by: Marek Vasut <marex@denx.de>

* arm: socfpga: clock: Clean up pll_config.hMarek Vasut2015-08-08-1/+7
| | | | | | | | | | | | | | | | | | | | | | | Extract the clock configuration horribleness caused by pll_config.h in the following manner. First of all, introduce a few new accessors which return values of various clocks used in clock_manager.c and use them in clock_manager.c . These accessors replace those few macros which came from pll_config.h originally. Also introduce an accessor which returns the struct cm_config default configuration for the clock manager used in SPL. The accessors are implemented in a board-specific wrap_pll_config.c file, whose sole purpose is to include the qts-generated pll_config.h and provide only the necessary values to the clock manager. The purpose of this design is to limit the scope of inclusion for the pll_config.h , which thus far was included build-wide and poluted the namespace. With this change, the inclusion is limited to just the new wrap_pll_config.c file, which in turn provides three simple functions for the clock_manager.c to use.
