2014-02-20designware_i2c: Enhance DesignWare I2C driver address supportChin Liang See
Enhance the DesignWare I2C driver to support address length more than 1 byte. This enhancement is required as some I2C slave device such as EEPROM chip might have 16 bit address byte.

2014-02-19kbuild: use Linux Kernel build scriptsMasahiro Yamada
Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.

2014-02-19kbuild: change out-of-tree buildMasahiro Yamada
This commit changes the working directory where the build process occurs. Before this commit, build process occurred under the source tree for both in-tree and out-of-tree build. That's why we needed to add $(obj) prefix to all generated files in makefiles like follows: $(obj)u-boot.bin: $(obj)u-boot Here, $(obj) is empty for in-tree build, whereas it points to the output directory for out-of-tree build. And our old build system changes the current working directory with "make -C <sub-dir>" syntax when descending into the sub-directories. On the other hand, Kbuild uses a different idea to handle out-of-tree build and directory descending. The build process of Kbuild always occurs under the output tree. When "O=dir/to/store/output/files" is given, the build system changes the current working directory to that directory and restarts the make. Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>" syntax for descending into sub-directories. (We can write it like "make $(obj)=<sub-dir>" with a shorthand.) This means the current working directory is always the top of the output directory. Signed-off-by: Masahiro Yamada <[email protected]> Tested-by: Gerhard Sittig <[email protected]>

2014-02-07MMC: DWMMC: Correct the CLKDIV register valueRajeshwari S Shinde
This patch corrects the divider value written to CLKDIV register. Since SDCLKIN is divided inside controller by the DIVRATIO value set in the CLKSEL register, we need to use the same output clock value to calculate the CLKDIV value. as per user manual: cclk_in = SDCLKIN / (DIVRATIO + 1) Input parameter to mmc_clk is changed to dwmci_host, since we need the same to read DWMCI_CLKSEL register.

2014-02-07net/designware: make driver compatible with data cacheAlexey Brodkin

2014-02-07net/designware - switch driver to phylib usageAlexey Brodkin
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".

2014-02-07net/designware: add explicit reset of {tx|rx}_currdescnumAlexey Brodkin
Driver "init" function might be called multiple times. On every "init" Tx/Rx buffer descriptors are initialized: "descs_init" -> "{tx|rx}_descs_init". In its turn those init functions set MAC's "{tx|rx}desclistaddr" to point on the first buffer descriptor in the list. So CPU to start operation from the first buffer descriptor as well after every "init" we have to reset "{tx|rx}_currdescnum".

When ARCH_DMA_MINALIGN is greater than header size of the bit file, and buf is not aligned, new_buf address became greater then buf_start address and the load_word loop corrupts bit file data. A work around is to decrease new_buf of ARCH_DMA_MINALIGN, it might corrupt data before buf but permits to load correctly.
