// lmb_add seqeunce 
1) First 0xfdea0320 - 0xffffffff is requested and this is being added at rgn[0]
2) Next 0x9e800000-0xa47fffff is requested, this is being added at rgn[0] and rgn[0] of step 1 is shifted to rgn[1]
3) next 0xfcea0000 - FCEA4000 is requested, this is being added to rgn[1], and rgn[1] of step [2] shifted to rgn[2].
 reserved[0]    [0x9e800000-0xa47fffff], 0x06000000 bytes flags: 4
 reserved[1]    [0xfcea0000-0xFCEA4000], 0x00004000 bytes flags: 0
 reserved[2]    [0xfdea0320-0xffffffff], 0x0215fce0 bytes flags: 0
 ^^ How lpm_dump looks after after step 3
 4) next 0xFCEA4000 to 0xffffffff is requested, Since this coalesced with rgn[1], So at below this is being added
 https://elixir.bootlin.com/u-boot/latest/source/lib/lmb.c#L272
 5) Next we check with next range (https://elixir.bootlin.com/u-boot/latest/source/lib/lmb.c#L281) but this check fails because both 
 rgn has different base.  
 6) Ideally at step 5) we should check for overlap between next rng and this rng
