[PATCH] arm defconfig binary size reduction

[PATCH] arm defconfig binary size reduction

[Sascha Hauer]

With 64bit file support some defconfig builds are getting bigger than
their specififed maximum size of 256Kb. Use the tlsf allocator for
them which is smaller in binary size

[PATCH 1/2] ARM defconfigs: Use TLSF malloc on defconfigs getting too big

[Sascha Hauer]

Several boards are getting bigger than their specified maximum binary
size of 256Kb. Enable the TLSF allocator for them which is smaller
than the original dlmalloc. The changed defconfigs are:

eukrea_cpuimx25_defconfig
eukrea_cpuimx35_defconfig
eukrea_cpuimx51_defconfig
usb_a9260_defconfig
usb_a9263_128mib_defconfig
usb_a9263_defconfig
usb_a9g20_128mib_defconfig
usb_a9g20_defconfig

[PATCH 2/2] ARM at91sam9m10g45ek: Enable lzo decompression

[Sascha Hauer]

This results in a binary size reduction since now the default
environment gets compressed.
