linux-toradex.git/arch/arc/boot/Makefile, branch v3.19 Linux kernel for Apalis and Colibri modules ARC: [build] Allow uncompressed uImage 2013-04-09T06:51:15+00:00 Vineet Gupta vgupta@synopsys.com 2013-03-22T16:34:27+00:00 104058ede714d3d84f27025a7b5467c6bb137ffd The existing uImage target always generates gzip compressed image which drags bootup for some very slow FPGA customer boards. So introduce seperate make targets:uImage.{bin,gz} with uncompressed being default. Also tie gz generation to CONFIG_KERNEL_GZIP, which a platform can select in it's Kconfig if it wishes gz to be default. Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

The first 2 have been fixed in subsequent patches. Due to the nature of the 750 and 770, it is not possible to build for both together, w/o special runtime glue code which would hurt performance.

Arnd in his review pointed out that arch Kconfig organisation has several
deficiencies:

* Build time entries for things which can be runtime extracted from DT
  (e.g. SDRAM size, core clk frequency..)
* Not multi-platform-image-build friendly (choice .. endchoice constructs)
* cpu variants support (750/770) is exclusive.

The first 2 have been fixed in subsequent patches.
