Benjamin Herrenschmidt	803ee9ef35	Makefile: Improve clean a bit Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>	5 years ago
Benjamin Herrenschmidt	7bc118c7db	console: Move console files console.c goes to a new lib/ where we'll store other general utilities and console.h goes to include/ Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>	5 years ago
Benjamin Herrenschmidt	a87b86e54f	console: Replace putstr with puts It makes things a bit more standard and a bit nicer to read without all those strlen(). Also console.c takes care of adding the carriage returns before the linefeeds. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>	5 years ago
Benjamin Herrenschmidt	88b28a7b17	console: Improve putchar(), add puts() Make putchar() match a standard prototype and add puts() Also make puts() add carriage returns before linefeeds so the users don't have to do it all over the place.

Benjamin Herrenschmidt	c5f5f50738	hello_world: Use new headers and frequency from syscon This uses the new header files for register definitions and extracts the core frequency from syscon rather than hard coding it. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>	5 years ago
Benjamin Herrenschmidt	3687486d36	Update hello_world for 100Mhz clock Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>	5 years ago
Paul Mackerras	102b304db7	Merge remote-tracking branch 'remotes/origin/master'	5 years ago
Paul Mackerras	cf4dfeca36	Change the default cross compiler prefix to powerpc64le-linux-gnu- That is what is used by the packaged cross-compilers on (at least) Fedora and Ubuntu. Signed-off-by: Paul Mackerras <paulus@ozlabs.org>	5 years ago
Michael Neuling	fc5f7506f8	Add calls to dis/enable potato uart IRQ Signed-off-by: Michael Neuling <mikey@neuling.org>	5 years ago
Anton Blanchard	06b28be577	hello_world: Use Makefile automatic variables Fix a few whitespace issues while here. Signed-off-by: Anton Blanchard <anton@linux.ibm.com>	5 years ago
Paul Mackerras	04ec2115ad	hello_world: Use ldcix/stdcix to access UART This is one step towards ultimately removing the address-based cache inhibit hack from dcache.vhdl. Signed-off-by: Paul Mackerras <paulus@ozlabs.org>	5 years ago
Paul Mackerras	abefafd70b	hello_world: Adjust header inclusions and Makefile Currently hello_world fails to build with distro cross compiler packages such as Debian gcc-powerpc64-linux-gnu, because it doesn't provide string.h or unistd.h. In fact we don't need them, we just need stddef.h. This adds #include <stddef.h> to console.h to get size_t defined. We also add #include "console.h" to console.c. The hello_world Makefile currently hard-codes CROSS_COMPILE on non-PPC machines. This means that a command like: $ CROSS_COMPILE=powerpc64le-linux-gnu- make doesn't do what you expect; it just tries to use powerpc64le-linux-gcc regardless. Adding a '?' makes it do what one expects. Signed-off-by: Paul Mackerras <paulus@ozlabs.org>	5 years ago
Michael Neuling	96fbd61de8	Breakout the console code so it can be reused. No functional change. Signed-off-by: Michael Neuling <mikey@neuling.org>	5 years ago
Anton Blanchard	75f3614776	hello_world updates Shrink hello_world a bit (from 12kB to 8kB). Include the built images Add 0x10 and 0x100 entry points Signed-off-by: Anton Blanchard <anton@linux.ibm.com>	5 years ago
