mtk-20170518/target/linux/ramips/rt3883, branch master MTK 20170518 : Mediatek SDK based on OpenWRT Barrier Breaker kernel: only optimized for size if small_flash 2018-07-12T16:15:32+00:00 Mathias Kresin dev@kresin.me 2018-07-09T18:48:56+00:00 cf7154db07c0b8746be290c9e11dcab3c91d237e Add a new config option to allow to select the default compile optimization level for the kernel. Select the optimization for size by default if the small_flash feature is set. Otherwise "Optimize for performance" is set. Add the small_flash feature flag to all (sub)targets which had the optimization for size in their default kernel config. Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new setting. Exceptions to the above are: - lantiq, where the optimization for size is only required for the xway_legacy subtarget but was set for the whole target - mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have plenty of space and an optimization for size doesn't make much sense - rb532, which has 128MByte flash Signed-off-by: Mathias Kresin <dev@kresin.me> 
Add a new config option to allow to select the default compile
optimization level for the kernel.

Select the optimization for size by default if the small_flash feature is
set. Otherwise "Optimize for performance" is set.

Add the small_flash feature flag to all (sub)targets which had the
optimization for size in their default kernel config.

Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new
setting.

Exceptions to the above are:

  - lantiq, where the optimization for size is only required for the
    xway_legacy subtarget but was set for the whole target
  - mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have
    plenty of space and an optimization for size doesn't make much sense
  - rb532, which has 128MByte flash

ramips: add dwr-512 jboot firmware configuration 2018-04-08T07:51:06+00:00 Giuseppe Lippolis giu.lippolis@gmail.com 2018-04-05T16:01:41+00:00 1680ae7eae2602dd85463a71f88d0012b236bff7 The previous fw version require the replacement of the stock bootloader with u-boot. This prevent an easy stock restore of the original fw. Now a proper fw util has been developed to manage the stock jboot bootloader. Therefore make sense have a fw image for the stock bootloader. The old fw configuration (u-boot) is not compatible with the new one and will not be supported anymore. So at the end 2 image can be generated: 1) factory image with jboot bootloader openwrt-ramips-rt305x-dwr-512-b-squashfs-factory.bin 2) sysupgrade image with jboot bootloader openwrt-ramips-rt305x-dwr-512-b-squashfs-sysupgrade.bin Signed-off-by: Giuseppe Lippolis <giu.lippolis@gmail.com>
