* ARM bootm: remove now obsolete argsSascha Hauer2011-11-291-29/+0

* armlinux: cleanup linux varsSascha Hauer2011-11-291-27/+65
| | | | | | | | | | | | arch_number is currently exported to the environment but not read back on boot time which is rather confusing. system_rev and system_serial are not exported to the environment but can be set in board specific code. This patch exports all these variables to the environment and reads them back on boot time. All variables get a armlinux_ prefix, so the arch_number environment variable gets renamed.

* | | spi/altera_spi: Add cs_change supportFranck Jullien2011-11-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux kernel says (spi.h) : * All SPI transfers start with the relevant chipselect active. Normally * it stays selected until after the last transfer in a message. Drivers * can affect the chipselect signal using cs_change. * * (i) If the transfer isn't the last one in the message, this flag is * used to make the chipselect briefly go inactive in the middle of the * message. Toggling chipselect in this way may be needed to terminate * a chip command, letting a single spi_message perform all of group of * chip transactions together. * * (ii) When the transfer is the last one in the message, the chip may * stay selected until the next transfer. On multi-device SPI busses * with nothing blocking messages going to other devices, this is just * a performance hint; starting a message to another device deselects * this one. But in other cases, this can be used to ensure correctness. * Some devices need protocol transactions to be built from a series of * spi_message submissions, where the content of one message is * determined by the results of previous messages and where the whole * transaction * ends when the chipselect goes intactive. In other words, cs_change changes the default chipselect *behavior*. Support of cs_change is necessary to implement the mci spi driver. This patch also fix few things: Passing the bus number to the brand new master device. Disable chipselect during master->setup.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building sandbox with ccache, one would hit warnings such as: warning: 'struct mmsghdr' declared inside parameter list on random files; a way to reproduce this issue is to build a simple file doing just: #include <sys/socket.h> int main(void) { return 0; } gcc -Wall -P -c -o foo foo.c But actually the -P flag is only useful when generating non-C files, such as linker scripts in the case of barebox. Removing the -P flag from all the gcc invocations, except when generating .lds files makes the warning go away. It turns out that this is what linux/scripts/Makefile.build also does nowadays.
