* omap-common: SYS_BOOT fallback logic correction and support for more devicesPaul Kocialkowski2015-08-28-10/+22
| | | | | | | | | | | | | | | | | | | | | The SYS_BOOT-based fallback shouldn't only check for one of the conditions of use and then let the switch/case handle each boot device without enforcing the conditions for each type of boot device again. For instance, this behaviour would trigger the fallback for UART when BOOT_DEVICE_UART is defined, CONFIG_SPL_YMODEM_SUPPORT is enabled (which should be a show-stopper) and e.g. BOOT_DEVICE_USB is enabled and not CONFIG_SPL_USB_SUPPORT. Separating the logic for USB and UART solves this. In addition, this adds support for more peripheral devices (USBETH and CPGMAC) to the fallback mechanism. Note that the USBETH boot device should always be different from the USB boot device (each should match a different bootrom handoff case).

* ARM: DRA74-evm: Use SMA_1 spare register to workaround DP83865 phy on SR2.0Nishanth Menon2015-08-28-0/+9
| | | | | | | | | | | | | | | | | | | DP83865 ethernet phy used on DRA74x-evm is quirky and the datasheet provided IODELAY values for standard RGMII phys do not work. Silicon Revision(SR) 2.0 provides an alternative bit configuration that allows us to do a "gross adjustment" to launch the data off a different internal clock edge. Manual IO Delay overrides are still necessary to fine tune the clock-to-data delays. This is a necessary workaround for the quirky ethernet Phy we have on the platform. NOTE: SMA registers are spare "kitchen sink" registers that does contain bits for other workaround as necessary as well. Hence the control for the same is introduced in a generic SoC specific, board generic location. Signed-off-by: Nishanth Menon <nm@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>

| | | | | | | | | | | | | | | | | This patch moves pxa to the common timer functions added in commit 8dfafdd - Introduce common timer functions <Rob Herring> The (removed) pxa timer code (specifically __udelay()) could deadlock at the 32-bit boundary of get_ticks(). get_ticks() returned a 32-bit value cast up to a 64-bit value. If get_ticks() + tmo in __udelay() crossed the 32-bit boundary, the while condition became unconditionally true and locked the processor. Rather than patch the specific pxa issues, simply move everything over to the common code.

| | | | | | | | | | | | | | Since commit 3ff46cc42b9d73d0 ("arm: relocate the exception vectors") pxa does not boot anymore. Add a specific relocate_vectors macro that skips the vector relocation, as the pxa SoC does not provide RAM at the high vectors address (0xFFFF0000), and (0x00000000) maps to ROM.

Under certain conditions this can cause the system to deadlock. " Recommended workaround is as follows: Do both of the following: 1) Do not use the write-back no-allocate memory type. 2) Do not issue write-back cacheable stores at any time when the cache is disabled (SCTLR.C=0) and the MMU is enabled (SCTLR.M=1). Because it is implementation defined whether cacheable stores update the cache when the cache is disabled it is not expected that any portable code will execute cacheable stores when the cache is disabled. For implementations of Cortex-A15 configured without the “L2 arbitration register slice” option (typically one or two core systems), you must also do the following: 3) Disable write-streaming in each CPU by setting ACTLR[28:25] = 0b1111 So, we provide an option to disable write streaming on OMAP5 and DRA7. It is a rare condition to occur and may be enabled selectively based on platform acceptance of risk. Applies to: A15 revisions r2p0, r2p1, r2p2, r2p3 or r2p4 and REVIDR[3] is set to 0. Note: certain unicore SoCs *might* not have REVIDR[3] not set, but might not meet the condition for the erratum to occur when they donot have ACP (Accelerator Coherency Port) hooked to ACE (AXI Coherency Extensions). Such SoCs will need the work around handled in the SoC specific manner, since there is no ARM generic manner to detect such configurations.

* exynos: Add support for springSimon Glass2015-08-05-0/+6
| | | | | | | | | | Spring is the first ARM-based HP Chromebook 11. It is similar to snow and it uses the same Samsung Exynos5250 chip. But has some unusual features. Mainline support for it has lagged snow (both in kernel and U-Boot). Now that the exynos5 code is common we can support spring just by adding a device tree and a few lines of configuration.

* exynos: Enable the debug UART in SPLSimon Glass2015-08-05-0/+5
| | | | | | | | As a debugging aid, allow UART3 to be used as a debug UART in SPL. This is a precursor to proper UART support, which requires a substantial refactor. Signed-off-by: Simon Glass <sjg@chromium.org>
