| | | | | | | | | | | | | | | | | | | | | | | | Move details of the L1 cache line sizes & total sizes into Kconfig, defaulting to 0. A new CONFIG_SYS_CACHE_SIZE_AUTO Kconfig entry is introduced to allow platforms to select auto-detection of cache sizes, and it defaults to being enabled if none of the cache sizes are set by the configuration (ie. sizes are all the default 0), and code is adjusted to #ifdef on that rather than on the definition of the sizes (which will always be defined even if 0).

* | Revert "image.h: Tighten up content using handy CONFIG_IS_ENABLED() macro."Masahiro Yamada2016-05-31-12/+57
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 56adbb38727320375b2f695bd04600d766d8a1b3. Since commit 56adbb387273 ("image.h: Tighten up content using handy CONFIG_IS_ENABLED() macro."), I found my boards fail to boot Linux because the commit changed the logic of macros it touched. Now, IMAGE_ENABLE_RAMDISK_HIGH and IMAGE_BOOT_GET_CMDLINE are 0 for all the boards. As you can see in include/linux/kconfig.h, CONFIG_IS_ENABLE() (and IS_ENABLED() as well) can only take a macro that is either defined as 1 or undefined. This is met for boolean options defined in Kconfig. On the other hand, CONFIG_SYS_BOOT_RAMDISK_HIGH and CONFIG_SYS_BOOT_GET_CMDLINE are defined without any value in arch/*/include/asm/config.h . This kind of clean-up is welcome, but the options should be moved to Kconfig beforehand. Moreover, CONFIG_IS_ENABLED(SPL_CRC32_SUPPORT) looks weird. It should be either CONFIG_IS_ENABLED(CRC32_SUPPORT) or IS_ENABLED(CONFIG_SPL_CRC32_SUPPORT). But, I see no define for CONFIG_SPL_CRC32_SUPPORT anywhere. Likewise for the other three. The logic of IMAGE_OF_BOARD_SETUP and IMAGE_OF_SYSTEM_SETUP were also changed for SPL. This can be a problem for boards defining CONFIG_SPL_OF_LIBFDT. I guess it should have been changed to IS_ENABLED(CONFIG_OF_BOARD_SETUP). In the first place, if we replace the references in C code, the macros IMAGE_* will go away. if (IS_ENABLED(CONFIG_OF_BOARD_SETUP) { ... } Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

| * Add a mailbox driver framework/uclassStephen Warren2016-05-26-0/+233
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A mailbox is a hardware mechanism for transferring small message and/or notifications between the CPU on which U-Boot runs and some other device such as an auxilliary CPU running firmware or a hardware module. This patch defines a standard API that connects mailbox clients to mailbox providers (drivers). Initially, DT is the only supported method for connecting the two. The DT binding specification (mailbox.txt) was taken from Linux kernel v4.5's Documentation/devicetree/bindings/mailbox/mailbox.txt.

| * Rename reset to sysresetStephen Warren2016-05-26-72/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The current reset API implements a method to reset the entire system. In the near future, I'd like to introduce code that implements the device tree reset bindings; i.e. the equivalent of the Linux kernel's reset API. This controls resets to individual HW blocks or external chips with reset signals. It doesn't make sense to merge the two APIs into one since they have different semantic purposes. Resolve the naming conflict by renaming the existing reset API to sysreset instead, so the new reset API can be called just reset.

Even after selecting this, there are few GPIOs which control these muxes that needs to be held high. 2) The clock to PHY is provided by a PLL-based clock synthesizer[2] connected via I2C. This needs to properly programmed and locked for PHY operation. And PHY needs to be reset before before being used, which is also held by a GPIO. 3) RMII mode needs to be selected.

On AM43x devices, the address of SPL entry point depends on the device type, i.e. whether it is secure or non-secure. Further, for non-secure devices, the SPL entry point is different between USB HOST boot mode, other "memory" boot modes (MMC, NAND) and "peripheral" boot modes (UART, USB) To add to the complexity, on secure devices, in addition to the above differences, the SPL entry point can change because of the space occupied by other components (other than u-boot or spl) that go into a secure boot image. To prevent the user from having to modify source files every time any component of the secure image changes, the value of CONFIG_SPL_TEXT_BASE has been set using a Kconfig option that is supplied in the am43xx_*_defconfig files Using the CONFIG options also enables us to do away with some compile time flags that were used to specify CONFIG_SPL_TEXT_BASE for different boot modes. On QSPI devices, the same problem described above occurs w.r.t. the address of the u-boot entry point in flash, when booting secure devices. To handle this, CONFIG_SYS_TEXT_BASE is also setup via a Kconfig option and the defconfig files.

But the code in the boot ROM stores the information about the boot media at the offset 0x28 before passing control to the SPL. For example, when booting from the SD card, the magic number written by the boot ROM is 0. And when booting from the SPI flash, the magic number is 3. NAND and eMMC probably have their own special magic numbers too. Currently the corrupted byte is a part of one of the instructions in the reset vectors table: b reset ldr pc, _undefined_instruction ldr pc, _software_interrupt <- Corruption happens here ldr pc, _prefetch_abort ldr pc, _data_abort ldr pc, _not_used ldr pc, _irq ldr pc, _fiq In practice this does not cause any visible problems, but it's still better to fix it. As a bonus, the reported boot media type can be later used in the 'spl_boot_device' function, but this is out of the scope of this patch.
