| * SPL: ARM: spear: Add SPL support for SPEAr600 platformStefan Roese2012-07-07-27/+1740
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds SPL support for SPEAr600. Currently only SNOR (Serial NOR) flash support is included. Other boot devices (NAND, MMC, USB ...) may be added with later patches. Tested on the STM SPEAr600 evaluation and x600 SPEAr600 boards.

| * Makefile: Add u-boot.spr build target (SPEAr)Stefan Roese2012-07-07-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | On x600 (SPEAr600) U-Boot is appended to U-Boot SPL. Both images are created using mkimage (crc etc), so that the ROM bootloader can check its integrity. Padding needs to be done to the SPL image (with mkimage header) and not the binary. Otherwise the resulting image which is loaded/copied by the ROM bootloader to SRAM doesn't fit. The resulting image containing both U-Boot images is called u-boot.spr.

| * arm: Don't use printf() in SPL buildsSimon Glass2012-07-07-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | raise() likes to call printf() if it is available, but in SPL builds it either is not available, or adds a large chunk to the resulting image size. So don't call it even if it is available. This change reduces SPL size from 10KB to 6.3KB on hawkboard, for example, using generic relocation.

| * net: Multiple updates/enhancements to designware.cStefan Roese2012-07-07-69/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the following changes to designware ethernet driver found on the ST SPEAr SoC: - Don't init MAC & PHY upon startup. This causes a delay, waiting for the auto negotiation to complete. And we don't want this delay to always happen. Especially not on platforms where ethernet is not used at all (e.g. booting via flash). Instead postpone the MAC / PHY configuration to the stage, where ethernet is first used. - Add possibility for board specific PHY init code. This is needed for example on the X600 board, where the Vitesse PHY needs to be configured for GMII mode. This board specific PHY init is done via the function designware_board_phy_init(). And this driver now adds a weak default which can be overridden by board code. - Use common functions miiphy_speed() & miiphy_duplex() to read link status from PHY. - Print status and progress of auto negotiation. - Print link status (speed, dupex) upon first usage.

This feature is enabled only for flashing operation i.e. when CONFIG_SPEAR_USBTTY is enabled. This has been tested on SPEAr320, SPEAr600 and SPEAr900 evaluation boards. Following figures show an estimate on the performance improvements. The test setup was a Linux host (not Windows) and involved measurement of only binary transfer time, through kermit. The flash erase and flash copy time would be unaffected by these patches. Another thing is this that the timings remained more or less same across ARM9 and Cortex based devices, hence reporting only one of the cases.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enabling autoneg avoids situation on few phys with fixed configuration. For example, in one situation, nfs boot timed out when phy configuration is 100Mbps. In another situtation, when traffic is directed to SPEAr, either thru cross-cable or thru switch, the TFTP or DHCP command in u-boot starts to timeout very often. When Autoneg is ON, same phys started working perfectly.

Default bootargs: - console=ttyAMA0,115200 - For environment present in NOR flash root=/dev/mtdblock3 - For environment present in NAND flash root=/dev/mtdblock7 - Removes "mem=" option 2. Introduces CONFIG_EXTRA_ENV_USBTTY as default usbtty env var even when usbtty is not selected 3. Add default definitions for nfsboot and ramboot 4. Add a new default environment variable(CONFIG_EXTRA_ENV_UNLOCK) for SPEAr310 and SPEAr320 Signifacance of CONFIG_EXTRA_ENV_USBTTY: This environment variable is important for flashing utility to work. So if somebody accidently erases the env sector then also this variable must be preserved so that flashing utility functions properly. Signifacance of CONFIG_EXTRA_ENV_UNLOCK: This env variable is read by the cfi driver to unlock all flash sectors. This is necessary because the Parallel NOR flash connected on the spear310 and spear320 boards, M28W64, has all its sectors in locked state at reset and these have to be unlocked explicitly before being erased or written.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While the u-boot code is running from the flash, it is essential that no access is made to the bss segment. This is due to the fact that .rel.dyn and .bss areas overlap and former contains information used in relocation. In SPEAr, this was not taken into consideration. As a result, while the relocation wasn't complete, dram_init populated an uninitialized global variable resulting in corruption of .rel.dyn area, which resulted in u-boot crash.

| * arm/km: remove calls to kw_gpio_* in board_early_init_fHolger Brunck2012-07-07-15/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These functions tried to access two static tables before relocation (board_early_init_f is executed before relocation). But these static tables lie in the bss section which is not valid before relocation. These accesses then overwrote some parts of u-boot binary before it was relocated. For the kmnusa build, this results in a corrupted important env variable (bootcmd) but it may be that some other parts of the u-boot binary are corrupted. This patch solves this problem by moving all the kw_gpio_* calls to board_init, which should be early enough in the boot sequence. The only calls that could not be moved is the one for the SOFT (bitbang) I2C, and they have been replaced by a direct access to the GPIO dataout Control register to set the two GPIOs as output.

| * arm/km: add implementation for read_dip_switchThomas Herzmann2012-07-07-4/+13
| | | | | | | | | | | | | | | | | | Add a function to read the dip_switch on kmcoge5un. If the switch is set the actual_bank is set to 0 and this SW is booted. Signed-off-by: Thomas Herzmann <thomas.herzmann@keymile.com> Signed-off-by: Holger Brunck <holger.brunck@keymile.com>
| * arm/km: support the 2 PCIe fpga resetsValentin Longchamp2012-07-07-4/+9
| | | | | | | | | | | | | | | | | | The PCIe FPGAs now have to support 2 resets: one for the non traffic affecting part (PCIe) and one for the traffic affecting part. When the FPGA is not reconfigured, we only reset the PCIe part. Signed-off-by: Valentin Longchamp <valentin.longchamp@keymile.com>
