* davinci_emac: hardcode 100Mbps for AM35xx and RMIIIlya Yanok2011-12-06-1/+2
| | | | | | | For some reason code setting the speed based on the PHY feedback causes troubles on AM3517 so hardcode 100Mbps for now. Signed-off-by: Ilya Yanok <yanok@emcraft.com>
* davinci_emac: fix for running with dcache enabledIlya Yanok2011-12-06-4/+42
| | | | | | | | | | | | DaVinci EMAC is present on TI AM35xx SoCs (ARMv7) which run with D-Cache enabled by default. So we have to take care and flush/invalidate the cache before/after the DMA operations. Please note that the receive buffer alignment to 32 byte boundary comes from the old driver version I don't know if it is really needed or alignment to cache line size is enough.

* arm926ejs: add noop implementation for dcache opsIlya Yanok2011-12-06-1/+76
| | | | | | | | Added noop implementation for dcache operations that will buzz about missing real implementation and disable the dcache. This fixes compilation of DaVinci EMAC driver on arm926ejs. Signed-off-by: Ilya Yanok <yanok@emcraft.com>

* davinci_emac: use internal addresses in buffer descriptorsIlya Yanok2011-12-06-9/+30
| | | | | | | | On AM35xx CPPI RAM had different addresses when accessed from the CPU and from the EMAC. We need to account this to deal with the buffer descriptors correctly. Signed-off-by: Ilya Yanok <yanok@emcraft.com>
* davinci_emac: move arch-independent defines to separate headerIlya Yanok2011-12-06-289/+319
| | | | | | | | | | | DaVinci EMAC is found not only on DaVinci SoCs but on some OMAP3 SoCs also. This patch moves common defines from arch-davinci/emac_defs.h to drivers/net/davinci_emac.h DaVinci specific PHY drivers hacked to include the new header. We might want to switch to phylib in future.

* omap4+: streamline CONFIG_SYS_TEXT_BASE and other SDRAM addressesAneesh V2011-12-06-15/+21
| | | | | | | | | | | | | | | | | | | | | | | | Change the CONFIG_SYS_TEXT_BASE and the addresses of SDRAM buffers used by SPL(heap and BSS) keeping in mind the following requirements: 1. Make sure that SPL's heap and BSS doesn't come in the way of Linux kernel, which is typically loaded at 0x80008000. This will be important when SPL directly loads kernel. 2. Align the CONFIG_SYS_TEXT_BASE between TI internal U-Boot and mainline U-Boot. This avoids a lot of confusion and allows for the inter-operability of x-loader, SPL, internal U-Boot, mainline U-Boot etc. The internal U-Boot's address can not be changed to that of mainline U-Boot as internal U-Boot doesn't have relocation and 0x80100000 used by mainline U-Boot will clash with kernel 3. Assume only a minimum amount of memory that may be available on any practical OMAP4/5 board in future too. We are assuming a minimum of 128 MB of memory Signed-off-by: Aneesh V <aneesh@ti.com>

* omap: remove I2C from SPLAneesh V2011-12-06-1/+0

* omap4460: fix TPS initializationAneesh V2011-12-06-10/+13
| | | | | | | | | | | TPS power IC is controlled using a GPIO (gpio_wk7). This GPIO should be maintained at logic 1 always. As such an internal pull-up on this pin will do the job, driving the GPIO outuput is not needed. This will avoid the need of using GPIO library in SPL and also may save some power.

* armv7: disable L2 cache in cleanup_before_linux()Aneesh V2011-12-06-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | We were not disabling external caches before jumping to kernel. We were flushing all caches including external caches and disabling caches globally in CP15 System Control register. Apparently this is not enough. The bootstrap loader in Linux kernel that does decompression enables data-caches again, flush them after use and disable them before jumping to kernel proper. However, it's not aware of the external caches. Since we have left external cache enabled, external cache will get used once caches are enabled globally, but it's not flushed because decompressor is not aware of external caches. When it jumps to kernel with caches disabled globally, we have stale data in the external cache and a coherency problem. This was breaking the boot for OMAP4 with latest mainline kernel. The solution is to disable external caches in cleanup_before_linux(). With this fix kernel is booting again. Cc: Albert Aribaud <albert.u.boot@aribaud.net> Signed-off-by: Aneesh V <aneesh@ti.com>
