Synchronized with git revision 82aa7b7f2b67dfdef90373b703bb8b2f33ea4e57



Full URL: https://github.com/mbedmicro/mbed/commit/82aa7b7f2b67dfdef90373b703bb8b2f33ea4e57/



1. Provide the required __end__ symbol

2. Call software_init_hook() if present, which in turn starts the RTOS



The fix was applied for all targets with a TOOLCHAIN_GCC_CR folder,

but it only works with LPC1768 and LPC4088 because of incomplete or

missing support for GCC_CR and/or the RTOS for the other targets.

Tested by running RTOS_1, RTOS_2 and RTOS_3 with LPC1768 and LPC4088.
