I have configured the kernel CONFIG_PHYSICAL_START=0x10000000 and in kernel boot parameter I have set mem=128M. In this scenario my kernel is not booting and it just stuck after uncompressing it. If I do not provide mem=128M boot parameter my kernel boots fine, but in that case I can not restrict kernel to use only 128M memory. Why supplying mem=128M causing kernel to fail.

Any kernel option else is configured, such as CONFIG_KERNEL_START and
CONFIG_RELOCATABLE?
Or any u-boot argument is reconfigured, such as 'bootm_low', 'bootm_mapsize' and
'bootm_size'.
