* net/designware - switch driver to phylib usageAlexey Brodkin2014-02-07-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this change driver will benefit from existing phylib and thus custom phy functionality implemented in the driver will go away: * Instantiation of the driver is now much shorter - 2 parameters instead of 4. * Simplified phy management/functoinality in driver is replaced with rich functionality of phylib. * Support of custom phy initialization is now done with existing "board_phy_config". Note that after this change some previously used config options (driver-specific PHY configuration) will be obsolete and they are simply substituted with similar options of phylib. For example: * CONFIG_DW_AUTONEG - no need in this one. Autonegotiation is enabled by default. * CONFIG_DW_SEARCH_PHY - if one wants to specify attached phy explicitly CONFIG_PHY_ADDR board config option has to be used, otherwise automatically the first discovered on MDIO bus phy will be used I believe there's no need now in "doc/README.designware_eth" because user only needs to instantiate the driver with "designware_initialize" whose prototype exists in "include/netdev.h".

* ARM: Remove unused stack and irq config definesRob Herring2012-09-01-8/+0
| | | | | | | | | | | CONFIG_STACKSIZE is not referenced anywhere except on AVR32, but present in most ARM board config files. IRQs are only enabled for 1 config, so remove the unused config options for IRQ and FIQ stack size as well.

* net: Multiple updates/enhancements to designware.cStefan Roese2012-07-07-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* SPEAr: Enable autoneg for ethernetShiraz Hashim2012-07-07-0/+1
| | | | | | | | | | | | | | | | 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.

* SPEAr: Change the default environment variablesVipin KUMAR2012-07-07-9/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch modifies the default environment variables as: 1. 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.

* st_smi: Add support for SPEAr SMI driverVipin KUMAR2012-07-07-3/+3
| | | | | | | | | | | | | | SMI is the serial memory interface controller provided by ST. Earlier, a driver exists in the u-boot source code for the SMI IP. However, it was specific to spear platforms. This commit converts the same driver to a more generic driver. As a result, the driver files are renamed to st_smi.c and st_smi.h and moved into drivers/mtd folder for reusability by other platforms using smi controller peripheral.

* Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk2010-10-26-1/+0
| | | | | | | | | | | | | | | | | | CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not being able to use "sizeof(struct global_data)" in assembler files. Recent experience has shown that manual synchronization is not reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into GENERATED_GBL_DATA_SIZE which gets automatically generated by the asm-offsets tool. In the result, all definitions of this value can be deleted from the board config files. We have to make sure that all files that reference such data include the new <asm-offsets.h> file. No other changes have been done yet, but it is obvious that similar changes / simplifications can be done for other, related macro definitions as well.
